You already converted mass to moles for the reactants now convert mass to moles for the product, copper 0.71 g Cu equals

skelet666 [1.2K]

Answer: 0.011 moles.

Explanation:-

To calculate the moles, we use the equation:

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

Given :

Mass of copper = 0.71 g

Molar mass of copper = 63.5 g/mol

Putting i the values, we get:

$\text{Number of moles of copper}=\frac{0.71g}{63.5g/mol}=0.011moles$

Thus the number of moles of copper in 0.71 g of copper is 0.011 moles.
