Atank contains 12.0 g of chlorine gas (cl2) at a temperature of 81 °c and an absolute pressure of 5.90 × 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 29 °c and, due to a leak, the pressure has dropped to 2.60 × 10^5 pa. how many grams of chlorine gas has leaked out of the tank?
