Answer: 0.011 moles.
Explanation:-
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
Given :
Mass of copper = 0.71 g
Molar mass of copper = 63.5 g/mol
Putting i the values, we get:
[tex]\text{Number of moles of copper}=\frac{0.71g}{63.5g/mol}=0.011moles[/tex]
Thus the number of moles of copper in 0.71 g of copper is 0.011 moles.
