A 2.50-L volume of hydrogen measured at -196 degree C is warmed to 100 degree C. Calculate the volume of the gas at the higher temperature, assuming no change in pressure. A 20.0-L cylinder containing 11.34 kg of butane, C4H10, was opened to the atmosphere. Calculate the mass of the gas remaining in the cylinder if it were opened and the gas escaped until the pressure in the cylinder was equal to the atmospheric pressure, 0.983 atm, and a temperature of 27 degree C. What is the molar mass of a gas if 0.0494 g of the gas occupies a volume of 0.100 L at a temperature 26 degree C and a pressure of 307 torr? The density of a certain gaseous fluoride of phosphorus is 3.93 g/Lat STP. Calculate the molar mass of this fluoride and determine its molecular formula. A 36.0-L cylinder of a gas used for calibration of blood gas analyzers in medical laboratories contains 350 g CO2, 805 g O2, and 4, 880 g N2. At 25 degrees C, what is the pressure in the cylinder in atmospheres? What volume of O2 at STP is required to oxidize 8.0 L of NO at STP to NO2? What volume of NO2 is produced at STP?
