Question

0.71 g Cu equals how many moles

Answer 1

Answer: 0.011 moles

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

given mass = 0.71 g

Molar mass= 63.5 g

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

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

The number of moles is 0.011 moles.
