Question

A sample of carbon tetrachloride (CCl4) contains 3 moles of the substance. How many atoms are there in the sample?

Answer 1

Answer:

1.806 × 10²⁴ atoms

Explanation:

To obtain the number of atoms a substance contain, we have to multiply the number of moles in that substance (n) by Avogadro's number, which is 6.02 × 10²³.

According to this question, a sample of carbon tetrachloride (CCl4) contains 3 moles of the substance. The number of atoms in CCl4 is calculated thus:

number of atoms = 3 × 6.02 × 10²³

number of atoms = 18.06 × 10²³

number of atoms = 1.806 × 10²⁴ atoms.
