Answer:
3.16x10²⁵ molecules
Explanation:
1 mol refers to the amount of a substance. The amount of C₂H₆ molecules (or any other substance) that are in one mol is given by Avogadro's number:
- 1 mol contains 6.023x10²³ particles (be it atoms, molecules or ions).
With that in mind we can calculate how many molecules are there in 52.5 moles:
- 52.5 mol * 6.023x10²³ molecules/mol = 3.16x10²⁵ molecules
