Cl2 + 2HBr → 2HCl + Br2

Assuming STP, what is the volume of bromine gas produced if 82.60 liters of Cl2 react with HBr?

2 answers

the same number of mols of Br2 as of Cl2
Therefore the same number of liters at STP, 82.60 liters
(about 22.4 mols/liter at STP)
sorry, mind failing, 22.4 liters /mol
luckily irrelevant for this problem
