3 moles of chlorine molecule Cl₂ has a mass of ?

The mass of given amount of chlorine gas is 213 grams

Explanation:

To calculate the number of moles, we use the equation:

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

Molar mass of chlorine gas = 71 g/mol

Moles of chlorine gas = 3 moles

Putting values in above equation, we get:
