Well if the atomic weight of chlorine gas is 70.906, that means one mole of it is going to have a mass of 70.906 grams. So for every mole, we have 70.90 grams, we have . 07 moles, so we’ll multiply .

## How do you calculate moles of chlorine?

The mass of one mole of chlorine gas is its molar mass, and can be determined by multiplying its subscript by the molar mass of chlorine (atomic weight on the periodic table in g/mol), which is 35.45 g/mol .

## How much is a mole of chlorine?
