how to find moles, when given molar mass

Answers

Answer 1

To find moles when given the molar mass, you can use the concept of molar mass as a conversion factor.Molar mass represents the mass of one mole of a substance, expressed in grams per mole (g/mol).

To calculate moles, divide the given mass of the substance by its molar mass. The equation is:

moles = mass / molar mass

For example, if you have 56 grams of carbon dioxide (CO2) and want to find the number of moles, you need to know the molar mass of CO2, which is approximately 44 g/mol. Using the equation above:

moles = 56 g / 44 g/mol

moles ≈ 1.27 mol

Therefore, there are approximately 1.27 moles of carbon dioxide in 56 grams.

Answers

The correct options that apply during a chemical change are:

A) One atom or more changes into atoms of another element.

B) New substances with different properties are formed.

C) Solids, liquids, or gases may form. Option A, B and C

During a chemical change, the arrangement of atoms in molecules is altered, resulting in the formation of new substances with different chemical properties. This is represented by option B. For example, when hydrogen gas (H₂) reacts with oxygen gas (O₂), a chemical change occurs, and water (H₂O) is formed. The properties of water, such as boiling point, density, and chemical reactivity, are distinct from those of its constituent elements.

Additionally, during a chemical change, atoms can rearrange to form molecules of different elements, as indicated in option A. For instance, during a nuclear reaction, such as radioactive decay, the nucleus of an atom can change, leading to the formation of atoms of different elements.

Option C is also correct. Depending on the specific reaction conditions, chemical changes can result in the formation of solids, liquids, or gases. For example, when a metal reacts with an acid, such as zinc with hydrochloric acid, a gas (hydrogen) is produced.

Options D and E are not universally applicable to all chemical changes. While some reactions may release heat energy (exothermic reactions), others may absorb heat energy (endothermic reactions). The requirement for heating or the release of heat depends on the specific reaction and its energy considerations.

In summary, during a chemical change, atoms can change into atoms of another element (A), new substances with different properties are formed (B), and solids, liquids, or gases may form (C).

O The average kinetic energy of A is greater than that of B.
O The average kinetic energy of B is greater than that of A.
O The average kinetic energy of both samples is equal.
O The average kinetic energy does not determine the direction of heat transfer.

Answers

The direction of heat transfer between two samples of carbon depends on their temperature difference, and not solely on their average kinetic energy. While the average kinetic energy of a substance is related to its temperature, it is not the determining factor for the direction of heat transfer.

When two samples of carbon come into contact, a heat transfer will occur between sample A and sample B. The direction of heat transfer is dependent on the temperature difference between the samples. Heat transfer always flows from a hotter object to a cooler object, so if sample A is hotter than sample B, heat will flow from A to B. If sample B is hotter than sample A, heat will flow from B to A.
The average kinetic energy of the molecules in a substance is related to its temperature. The higher the average kinetic energy, the higher the temperature of the substance. However, the average kinetic energy does not determine the direction of heat transfer.
It is possible for a substance with a lower average kinetic energy (and therefore a lower temperature) to transfer heat to a substance with a higher average kinetic energy (and therefore a higher temperature). This can occur if the substance with the lower temperature has a greater heat capacity, which means it can absorb more heat without a significant increase in temperature.

“a 5 carat diamond has a mass of 1.000 g. If the gemstone displaces a liquid from 1.00 mL to 1.30 mL, what is the density of the diamond?”

Answers

A 5 carat diamond has a mass of 1.000 g. If the gemstone displaces a liquid from 1.00 mL to 1.30 mL, and the density of the diamond is 3.33 g/mL

To calculate the density of the diamond, we can use the formula:

Density = Mass / Volume

Given that the mass of the diamond is 1.000 g and it displaces a liquid from 1.00 mL to 1.30 mL, we can substitute these values into the formula:

Density = 1.000 g / (1.30 mL - 1.00 mL)

By subtracting the initial volume from the final volume, we find:

Density = 1.000 g / 0.30 mL

Performing the division, we obtain:

Density = 3.33 g/mL

Therefore, the density of the diamond is 3.33 g/mL.

It's important to note that the units for density are grams per milliliter (g/mL) because the mass is given in grams and the volume is given in milliliters.

Understanding and applying the formula for density allows us to determine the mass per unit volume of a substance. In this case, the density provides information about how much mass is contained within a given volume for the diamond.

C. 80.07g SO3
D. 32 LSO3

Answers

The correct answer is B. 8 molecules [tex]SO_3[/tex]. Option B

In the given reaction:

S(s) + [tex]O_2[/tex](g) → [tex]SO_3[/tex](g)

The stoichiometric coefficient in front of the [tex]SO_3[/tex]molecule is 8, which indicates that 8 molecules of [tex]SO_3[/tex]are formed as a product. This coefficient represents the ratio of the number of molecules involved in the reaction.

Option A (8 atoms [tex]SO_3[/tex]) is incorrect because it only mentions the number of atoms, not molecules. The stoichiometric coefficient does not represent the number of atoms, but rather the number of molecules.

Option C (80.07g [tex]SO_3[/tex]) is incorrect because it mentions a specific mass. The stoichiometric coefficient does not directly represent the mass of the substance, but rather the relative amount of molecules involved in the reaction.

Option D (32 [tex]SO_3[/tex]) is incorrect because it mentions a specific volume. The stoichiometric coefficient does not directly represent the volume of the substance, but rather the relative amount of molecules involved in the reaction.

Therefore, the correct way to describe the [tex]SO_3[/tex]component in the reaction is option B: 8 molecules [tex]SO_3[/tex]. This represents the ratio of the number of molecules of [tex]SO_3[/tex]that are produced in the reaction.

Option B
