Answer: 0.011 moles

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number
6.023* 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}=(0.71g)/(63.5g/mol)=0.011moles

The number of moles is 0.011 moles.
