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
