Answer : The mass of copper is 217.3 grams.

Explanation : Given,

Moles of copper = 3.42 mole

Molar mass of copper = 63.55 g/mole

Formula used :

$\text{Moles of copper}=\frac{\text{Mass of copper}}{\text{Molar mass of copper}}$

Now put all the given values in this formula, we get:

$3.42mole=\frac{\text{Mass of copper}}{63.55g/mole}$

$\text{Mass of copper}=217.3g$

Therefore, the mass of copper is 217.3 grams.
