Explanation:

Step1: Recall chlorine gas formula

Chlorine gas is $Cl_2$.

Step2: Find atomic mass of chlorine

The atomic mass of chlorine ($Cl$) is approximately 35 g/mol.

Step3: Calculate molar - mass of $Cl_2$

The molar - mass of $Cl_2$ is $2\times35=70$ g/mol. So, the mass of one mole of chlorine gas is 70 grams.
