A chemical reaction produced 177.3 grams of chlorine has (Cl²). What was the volume of the gas?

Since there is so little information given, I will assume that we are at STP and i can use the conversion factor at STP--->> 22.4 Liters = 1 mol of gas

before we use this conversion, we need to convert the grams to moles using the molar mass of the molecule.

molar mass of Cl₂ = 35.5 x 2 = 71.0 g / mol

177.3 g (1 mol / 71.0 g) = 2.50 mol Cl₂

then we use the conversion to get the volume

2.50 mol Cl₂ (22.4 Liters / 1 mol) = 55.9 Liters
