Question

How many moles of Zn are in 0.535 g Zn?

Answer 1

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

Step-by-step explanation:

Answer 2

No. of moles = 0.0082

Step-by-step explanation:

To calculate the number of moles of a substance given its mass, we can use the following formula:

`\boxed{\mathrm{No. \ of \ moles = (Mass)/(Molar \ mass)}}`

The molar mass of zinc is 65 g/mol. The given mass of Zn in this question is 0.535 g. Using this information and the formula above, we can calculate the number of moles of Zn:

No. of moles =
`\mathrm{(0.535 \ g)/(65 \ g/mol)}`

= 0.0082 mol

Therefore, there are 0.0082 mol Zn in 0.535 g of Zn.
