A steel tank contains 232 g of ammonia gs (NH3 with molar mass 17.0 g/mol) at a pressure of 1.45 x 106 and a temperature of 45.4oC. (a) What is the volume of the tank in liters? (b) Later the temperature is 42.0oC and the pressure is 0.967 x 106 Pa. How many grams of gas have leaked out of the tank? (Ignore the thermal contraction of the tank.)
A cylinder 1.00m tall with inside diameter 0.120 m is used to hold propane gas(molar mass 44.1 g/mol) for use in a barbecue. It is initially filled in with gas until the gauge pressure is 1.30 x 10^6 Pa and the temperature is 22 degree Celsius. The temperature of the gas remains constant as it is partially emptied out of the tank, until the gauge pressure is 2.50 x 10^5 Pa. Calculate the mass of propane that has been used?
