Question

How many moles of zinc, Zn, are in 0.535g of zinc?

Answer 1

0.00818 mole of zinc. .............................................................................

Answer 2

Answer: The amount of zinc for a given amount are 0.0082 moles.

Step-by-step explanation:

To calculate the number of moles, we use the equation:

`\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}`

We are given:

Given mass of zinc = 0.535 g

Molar mass of zinc = 65.4 g/mol

Putting values in above equation, we get:

`\text{Moles of zinc}=(0.535g)/(65.4g/mol)=0.0082mol`

Hence, the amount of zinc for a given amount are 0.0082 moles
