Question

A necklace has 6g of diamond. How many atoms of carbon are present in it?

Answer 1

Answer:

Since 12 grams of carbon contains 1 mole of its atoms, 6 grams of it contains half a mole, that is, 3.01 x 10^23 atoms of it.

Answer 2

Answer:

3.011×10²³ atoms of carbon are present in 6g of the diamond.

Explanation:

We will understand this question through the concept of moles.

• The term "mole" refers to the quantity of a substance that contains the same number of elementary particles (ions, molecules, or atoms) as there are carbon atoms.

• Carbon makes up diamonds.
• Carbon has a molar mass of 12 grams.
• This indicates that there is a mole of carbon atoms in 12 grams of carbon.
• The mole mass is 6.022×10²³.
• Therefore, since 6 grams is half of 12 grams, there must be 3.011×10²³ atoms, or half a mole, in 6 grams.

So, 3.011×10²³ atoms of carbon are present in 6g of the diamond.
