The mass of the chlorine gas at the given condition is determined as 0.826 g.
Volume of a gas at STP
The volume of one mole of a gas at standard temperature and pressure is given as;
1 mole of a chlorine gas = 22.4 L = 22,400 mL
x mole = 265 mL
x = 265 mL/22,400 mL
x = 0.0118 mole
Mass of the gas
1 mole of chlorine gas = 70 g/mole
0.0118 mole = ?
= 0.0118 x 70g
= 0.826 g
