Answer:
3.118x10²⁴ ammonia molecules
Explanation:
First we convert the mass of ammonia to moles, using its molecular weight:
Molecular weight of ammonia = 17 g/mol
- 88.00 g ÷ 17 g/mol = 5.176 mol
Then we convert moles into molecules, using Avogadro's number:
- 5.176 mol * 6.023*10²³ molecules / mol = 3.118x10²⁴ molecules
