A steel tank contains 314 g of ammonia gs (NH3 with molar mass 17.0 g/mol) at a pressure of 1.55 x 106 and a temperature of 51.4oC.
(a) What is the volume of the tank in liters?
(b) Later the temperature is 45.5oC and the pressure is 0.975 x 106 Pa. How many grams of gas have leaked out of the tank? (Ignore the thermal contraction of the tank.)
