Diamond is a natural form of pure carbon. What number of atoms of carbon are in a 1.00-carat diamond (1.00 carat = 0.200 g)?

slega [8]

Answer:

1.004×10²²

Explanation:

The molar mass of carbon is 12 g/mol

which means that:

1 mole of carbon atoms has a mass of 12 grams.

Since, diamond is a allotrope of carbon.

Mass of 1.00-carat diamond in grams is:

1.00 carat = 0.200 g

Since, 1 mole of C contains 6.022×10²³ atoms of C

So,

12 grams contains 6.022×10²³ atoms of C

1 gram contains 6.022×10²³/ 12 atoms of C

0.200 gram contains (6.022×10²³/ 12)×0.200 atoms of C

Thus,

1 carat diamond contains 1.004×10²² atoms of C.

What is one example of an everyday molecule?

Tamiku [17]

Answer:

Hydrogen

Explanation:

Just to provide some background, an element is a pure substance consisting of only one type of atom. An atom is the smallest constituent of matter. All elements are comprised of a single type of atom (e.g., gold is composed of gold atoms, helium of helium atoms, phosphorus phosphorus, and so on).

A molecule is a group of two or more atoms. They can be the same atom (homonuclear), such as or different atoms (heteronuclear).

Some examples of homonuclear molecules include:

Hydrogen (H2)

Nitrogen (N2)

Phosphorus (P4)

Some examples of heteronuclear molecules include:

Carbon dioxide (CO2)

Sulfuric acid (H2SO4)

Methane (CH4)
