1- A gas sample has a pressure of 1.17 bar. What is this pressure in atm? Hint: 1 atm = 101.3 kPa = 1.013 bar = 760 torr = 760 mm Hg = 14.7 psi 2- A sample of gas has a volume of 474 mL at a pressure of 3.49 atm. The gas is compressed and now has a pressure of 7.72 atm. Predict if the new volume is greater or less than the initial volume, and calculate the...

A sample of methane gas at a pressure of 1.17 atm and a temperature of 23.8 °C, occupies a volume of 15.8 liters. If the gas is compressed at constant temperature to a volume of 5.62 liters, the pressure of the gas sample will be atm. A sample of oxygen gas at a pressure of 0.976 atm and a temperature of 22.7 °C, occupies a volume of 786 mL. If the gas is allowed to expand at constant temperature until...
A sample of gas at 760 torr and 2.8 L is compressed at constant temperature to the pressure at 3.5 atm. What is the final volume of the gas? My biggest problem with answering this question is the fact that I don't know what the "constant temperature" is..I know I'm using the combined gas law with formula: V2= p1v1/t1p2 * T2 and that p1=760 torr or 1 atm, v1=2.8L and p2=3.5 atm... Any help on this is very much appreciated.
