Answer 1

Answer:

50. 5mol

Explanation:

The mass of Zinc required = 3.30 kg = 3300 grams

The relation between moles and mass is:

$moles=\frac{mass}{atomicmass}$

Atomic mass of Zinc = 65.38g/mol

$molesofZinc=\frac{3300}{65.38}$

$molesofzinc=50.47mol$

The answer to three significant figures will be 50.5 mol
