Question

A cylinder of gas has a pressure of the gas is 3.59 atm and the T is -3.60 degree C. A 3.893 L sample was removed from the cylinder with a final pressure of 1076 mm Hg and a temperature of 12.37 degree C. What was the volume of the original sample? A cylinder of gas weighs 4.353 kg which is stored at 20.00 degree C under a pressure of 10.47 atm. A sample of gas at 0.00 degree C and 1 atm was drained from the tank, what is the volume of the sample? After the sample was removed the tank weighs 4.147 kg. What is the molecular weight of the gas? Calculate the molecular weight of: [4 each] Balance the following reactions by placing a number on each line, you must write the number one to demonstrate that you know the answer. Blank lines will be marked as incorrect.
