A tank contains 12.2 g of chlorine gas (Cl2) at a temperature of 84 °C and an absolute pressure of 5.60 × 105 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 26 °C and, due to a leak, the pressure has dropped to 3.20 × 105 Pa. How many grams of chlorine gas have leaked out of the tank?

  2. Convert g to mol by dividing g by molar mass. Convert Pa to atm. Use PV=nRT, R=0.0821 Latm/Kmol.
