Answer:
219.73 g
Step-by-step explanation:
The molecular formula of zinc (II) oxide is ZnO. This means its molar mass would be:
- Molar Mass of ZnO = (Atomic Mass of O) + (Atomic Mass of Zn)
- Molar Mass of ZnO = 16 + 65.38 = 81.38 g/mol
With that molar mass, we can convert moles into grams:
- mass = moles * molar mass
- mass = 2.70 moles * 81.38 g/mol = 219.73 g
