Identify the molar mass of a gas if of it occupies at STP.
1) At what pressure would a sample of gas occupy 8.96L if itoccupies 3.04L at 4.16atm? (Assume constant temperature)
2) A sample of gas originally occupies 26.22 L at 0C. what isits new volume when it is heated at 27C? (assume constantpressure)
3) what pressure would be required for helium at 25C to have thesame density as carbon dioxide at 25C and 1.00 atm?
4) At 46C a sample of ammonia gas exerts a pressure of 4.33 atm.what is the pressure when the volume of the gas is reduced toone-third of the original value at the same temperature?
5) A gas sample occupying a volume of 24.9 mL at a pressure of0.725 atm is allowed to expand at constant temperature until itspressure reaches 0.393 atm. what is its final volume?
