A steel tank contains 342 g of ammonia gs (NH3 with molar mass 17.0 g/mol) at a pressure of 1.13 x 106 and a temperature of 70.6oC.
(a) What is the volume of the tank in liters?
(b) Later the temperature is 60.3oC and the pressure is 0.729 x 106 Pa. How many grams of gas have leaked out of the tank? (Ignore the thermal contraction of the tank.)
