To find the mass of substance the equation is
[Container and Substance] + [Container] = [Substance]
True
False
Answer: FALSE
In order to find the mass of a substance you need to measure the container with the substance in it, and then take a second measurement with the container empty. You would then subtract the two measurements to find the total mass of the substance, you would not add as stated in the question.

Atomic elements have more than one atom in their basic unit. H, F, and P are some examples of atomic elements. H2, F2, and P4 are some examples of molecular elements. Molecular elements have more than one atom in their basic unit.
Answer:
Atomic elements exist with a single atom as their basic unit.
H, F, and P are some examples of atomic elements.
H2, F2, and P4 are some examples of molecular elements.
Molecular elements have more than one atom in their basic unit.
Explanation:
Atomic element exists as the smallest particle of an element that can take part in a chemical reaction. They exist with a single atom as their basic unit. The atomic number of an element is the number of protons present in the atomic nucleus of the element. Atomic elements are usually monoatomic such as H, F and P.
Molecular elements are the smallest particle that are capable of independent existence and still retains the chemical properties of those substances. They are capable of independent existence because they are diatomic. The combination of atoms of the same type produces a molecule of an element such as H₂, F₂, and P₂.

The density of gold is 19.3 g/cm3. What is the mass of 11.3 cm3 of gold? Show your work.
Answer:
218.09g
Explanation:
the formula for density is mass/volume
you have volume so rlly what you have is 19.3g/cm3=m/11.3cm3
so mass equals density x volume
and 19.3 x 11.3 = 218.09

You are on an alien planet where the names for substances and the units of measures are very unfamiliar. Nonetheless, you obtain 40 quibs of a substance called skvarnick. You can trade this skvarnick for gold coins, but the vendors all measure skvarnick in units of sleps; not quibs. 15 quibs is equal to 13 sleps. If you have 40 quibs of skvarnick, how many sleps do you have? Round your answer to the nearest tenth (one decimal place). Type only the number; not the number and unit. Your Answer:
If a cube has a volume of 25.0 mL, what mass, in grams, would it have to have to
be made of gold? Gold has a density of 19.3 g/mL. (Answer only the number with
the correct number of sigfigs) *
Answer:
482.5 grams
Explanation:
Given that,
Volume of a cube is 25 mL
The density of gold is 19.3 g/mL
We need to find the mass of the gold cube. We know that density is equal to the mass per unit volume. So,
[tex]d=\dfrac{m}{V}\\\\m=d\times V\\\\m=19.3\ g/mL\times 25\ mL\\\\m=482.5\ g[/tex]
So, the mass of the gold cube is 482.5 grams.
Convert 8.7 g to mg
Sabendo que os calores de combustão do enxofre monoclínico e do enxofre rômbico são, respectivamente, - 297,2 kJ/mol e - 296,8 kJ/mol, calcule a variação de entalpia na transformação de 1 mol de enxofre rômbico em enxofre monoclínico. S (mon.) + O2(g) SO2(g) ∆H1 = –297,2 kJ/mol S (rômb.) + O2(g) SO2(g) ∆H2 = –296,8 kJ/mol
Responda:
+ 0,9kJ / mol
Explicação:
Dados os calores de combustão do enxofre monoclínico e enxofre rômbico como - 297,2 kJ / mol e - 296,8 kJ / mol, respectivamente para a variação na transformação de 1 mol de enxofre rômbico em enxofre monoclínico conforme mostrado pela equação;
S (mon.) + O2 (g) -> SO2 (g)
Uma vez que são todos 1 mol cada, a mudança na entalpia será expressa como ∆H = ∆H2-∆H1
Dado ∆H2 = -296,8kJ / mol
∆H1 = -297,2kJ / mol
∆H = -296,8 - (- 297,2)
∆H = -296,8 + 297,2
∆H = 297,2-296,8
∆H = + 0,9kJ / mol
Portanto, a mudança na entalpia da equação é + 0,9kJ / mol
an object has a mass of 45.0 g and a volume of 4.0 ml. what is its density?
Answer:
The answer is
11.25 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]Density = \frac{mass}{volume} [/tex]
From the question
mass = 45 g
volume = 4 mL
Substitute the values into the above formula and solve for the density
We have
[tex]Density = \frac{45}{4} [/tex]
We have the final answer as
11.25 g/mLHope this helps you

A piece if stone has a mass of 24.595 grams and a volume of 5.34 cm ^3. What is the density of the stone
Answer:
The answer is
4.61 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass of stone = 24.595 g
volume = 5.34 cm³
The density of the stone is
[tex]density = \frac{24.595}{5.34} \\ = 4.605805243...[/tex]
We have the final answer as
4.61 g/cm³Hope this helps you
If the half life of Substance A is 0.5 years, how long would it take for 2 grams of substance A to remain given an initial mass of 16 grams?
Time taken is given by :
[tex]t=-\dfrac{1}{k}\dfrac{[A_t]}{[A_o]}[/tex] .......( 1 )
Also,
[tex]k = \dfrac{0.693}{t_{0.5}}\\\\\\k=\dfrac{0.693}{0.5}\\\\k=2\times 0.693\ year^{-1}[/tex]
Putting value of k in equation 1, we get :
[tex]t=\dfrac{1}{2\times 0.693}\times ln(\dfrac{2}{16})\\\\t=1.5\ years[/tex]
Therefore, time taken is 1.5 years.
Hence, this is the required solution.

Air is a mixture of gases. Air is composed of molecules such as oxygen, nitrogen and carbon dioxide. Air also contains atoms of noble gases such as neon, argon etc.
Air is composed of 21% molecular oxygen and 78% molecular nitrogen. Also, there is about 0.03% of carbon dioxide molecules in air.
Air is generally defined as a mixture of gases owing to the number of gaseous substances that compose air.
Also, there is a trace amount of noble gases which largely exists as monoatomic species in air.
