A tank contains 20 g of clorine gas (Cl2) at a temperature of83°C and an absolute pressure of 5.6 x 10 Pa. The mass permole of Cl, gas is 70.9 gmol-1. Determine the volume of the tank. (b) Later, the temperature of the tank has dropped to 35°Cand, due to a leak, the pressure has dropped to 3.8 × 10° Pa.How many grams of chlorine gas have leaked out of the tank?
