Answer:
No. of moles = 0.0082
Explanation:
To calculate the number of moles of a substance given its mass, we can use the following formula:
[tex]\boxed{\mathrm{No. \ of \ moles = \frac{Mass}{Molar \ mass}}}[/tex]
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 = [tex]\mathrm{\frac{0.535 \ g}{65 \ g/mol}}[/tex]
= 0.0082 mol
Therefore, there are 0.0082 mol Zn in 0.535 g of Zn.
