How many moles of zinc are in 4.70 kg of zinc?

There are 71.89 moles of Zinc in 4.70kg of Zinc

Explanation:

Information given;

- Calculate Number of moles

- Mass of Zinc

Before proceeding, it is important to know the definition of what molar mass is. Molar mass is defined as the mass in grams of one mole of a substance.

So it means one mole of Zinc would contain the molar mass in g.

The molar mass of Zinc is given as; 65.38g/mol

How many moles then in 4.70kg?

Upon converting to g, we have 4.7 *1000 = 4700g

1 mol = 65.38g

x mol = 4700g

Cross multiplication yields;

x = (1* 4700) / 65.38

x = 71.89 moles

It means that there are 71.89 moles of Zinc in 4.70kg of Zinc
