Question

A rigid tank contains 54.5 g of chlorine gas (Cl₂) at a temperature of 72 °C and an absolute pressure of 5.60×10^5 Pa. The mass per mole of Cl₂ is 70.9 g/mol. a) Determine the volume of the tank. b) Later, the temperature of the tank has dropped to 33 °C and, due to a leak, the pressure has dropped to 3.40×10^5 Pa. How many grams of chlorine gas has leaked out of the tank? (The mass per mole of Cl₂ is 70.9 g/mol.)
