A rigid tank contains 64.5 g of chlorine gas (Cl2) at a temperature of 75 °C and an absolute pressure of 5.10 × 105 Pa. Later, the temperature of the tank has dropped to 32 °C and, due to a leak, the pressure has dropped to 3.10 × 105 Pa. How many grams of chlorine gas have leaked out of the tank? (The mass per mole of Cl2 is 70.9 g/mol.)
