The Average Atomic Mass Of Carbon Is 12.01 Amu. One Isotope Of Carbon Has An Atomic Mass Of 12.00 Amuand
Answer 2

Answer:

B

Explanation:

So when you are calculating relative abundance you are actually calculating the atomic mass on the periodic table. So you are given the two isotopes of Carbon C-12 and C-13. Now you know that the atomic mass of C is 12.01 so you have to see that you have a lot more C-12 because the atomic mass is close to 12. Now you can calculate them out like this (0.99 x 12.0) +(.01 x 13.00)=12.01.

Which groups of the periodic table want to gain electrons? What kind(s) of elements are these groups

Answers

Answer:

Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.

Explanation:

The groups in the periodic table that want to gain electrons are groups; 15, 16 and 17. The members of these groups are mostly nonmetals.

The periodic table is composed of 18 groups and 8 periods of elements. Groups 1 - 13 are metals while groups 15 -18 are nonmetals. Group 14 consists of a mixture of metals and nonmetals.

The nonmetals usually accept electrons while metals electrons easily donate electrons. Elements of group 18 neither receive nor donate electrons because they have a complete octet.

Nonmetals of groups 15 -17 gain electrons easily.

Find the density of a liquid with a volume of 3.8 mL and a mass of 3.75 g

Answers

Answer:

The answer is

0.99 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} [/tex]

From the question

mass of liquid = 3.75 g

volume = 3.8 mL

Substitute the values into the above formula and solve for the density

The density is

[tex]density = \frac{3.75}{3.8} \\ = 0.98684210...[/tex]

We have the final answer as

0.99 g/mL

What does the force of gravity between two objects depend on?
A. The masses of the two objects and the distance between them
B. Only the mass of the smaller object and its distance from the
larger object
C. Only the masses of the two objects
D. The mass of the smaller object and the speed at which it's moving

Answers

Answer:

A

Explanation:

Answer:

Explanation:

The formula for the force of gravity is

F=G * m1 * m2 / r^2

G is a constant. It does not change with the use of the formula.  There are 2 masses, so the force depends on the masses.

The right hand side is divided by r^2. that's a distance. So that's the other quantity influencing the Force.

B: incorrect. Both objects have masses. That determines the force between them.

C: incorrect. It's also the distance between them.

D: incorrect. The formula contains nothing to indicate that velocity is important.

The answer is A

Calculate the mass of a piece of metal if its volume is 2.3 cm’and density is .486 g/cm3.
<-- Round to 3 digits
and show correct
units

Answers

Answer:

1.12 g.

Explanation:

From the question given above, the following were obtained obtained:

Volume (V) of metal = 2.3 cm³

Density (D) of metal = 0.486 g/cm³

Mass (m) of metal =..?

The density of a material is simply defined as the mass of the material per unit volume of the material. Mathematically, it is expressed as:

Density (D) = mass (m) / volume (V)

D = m/V

With the above formula, we can easily calculate the mass of the metal as shown below:

Volume (V) of metal = 2.3 cm³

Density (D) of metal = 0.486 g/cm³

Mass (m) of metal =..?

D = m/V

0.486 = m/2.3

Cross multiply

m = 0.486 × 2.3

m = 1.12 g

Therefore, the mass of the metal is 1.12 g.

Explanation:

a meter is a certain lenght. it does not change when you're somehwere else

A meter is the SI unit for length. This means that it is an international standard unit which is the same in America and France.

What is the SI unit of measurement?

The International System of Units (SI) is a French system. It is called French Système International d’Unités. It is an international decimal system of weights and measures. It has been derived from the metric system and extended it further.

It was adopted by the 11th General Conference on Weights and Measures (CGPM) in the year 1960, it is abbreviated as SI in all languages.

In the 19th and 20th centuries, rapid advances took place in the field of science. These developments resulted in the development of several overlapping systems of units of measurement. These were improvised by scientists to meet the practical needs of their disciplines.

The earlier international system that was developed for solving this issue was called the meter-kilogram-second (MKS) system. Then there was the CGPM system which added three new units in 1948. It used a unit of force, the newton.

It is defined as the force that can be given to a mass of one kilogram to provide it with an acceleration of one meter per second per second. Also a unit of energy, the joule was defined. It is the work done when the application of a newton on a point is displaced by one meter in the direction of the force.

There was also a unit of power, the watt. This is the power that gives to the energy of one joule. All of these three units were named after eminent scientists.

Therefore, a meter is the same in America as well as France.

calculate the number of atoms of sodium in a 4.5-gram sample

Answers

Answer:

1.18×10²³ atoms.

Explanation:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms.

From the above concept, 1 mole of sodium also contains 6.02×10²³ atoms.

1 mole of sodium = 23 g.

Thus,

23 g of sodium contains 6.02×10²³ atoms.

Therefore, 4.5 g of sodium will contain = (4.5 × 6.02×10²³)/23 = 1.18×10²³ atoms.

From the above calculation,

4.5 g of sodium contains 1.18×10²³ atoms.
