- What is the value of the ideal gas constant R if the volume is specified in milliliters rather than liters?arrow_forward5-38 What is the volume in liters occupied by 1.21 g of Freon-12 gas, CCI2F2, at 0.980 atm and 35°C?arrow_forward5-37 A sample of a gas at 77°C and 1.33 atm occupies a volume of 50.3 L. (a) How many moles of the gas are present? (b) Does your answer depend on knowing what gas it is?arrow_forward
- 5-46 Calculate the molar mass of a gas if 3.30 g of the gas occupies 660. mL. at 735 mm Hg and 27°C.arrow_forwardAmmonium chloride, NH4Cl, is a while solid. When heated to 325C, it gives a vapor that is a mixture of ammonia and hydrogen chloride. NH4Cl(s)NH3(g)+HCl(g) Suppose someone contends that the vapor consists of NH4Cl molecules rather than a mixture of NH3 and HCl. Could you decide between these alternative views on the basis of gas-density measurements? Explain.arrow_forwardWhich of the following gas samples would have the largest volume, if all samples are at the same temperature and pressure? a 263g of Xe; b 51023 molecules of H2; c 4.00moles of CO2; d they would all have the same volume.arrow_forward
- 5-34 A sample of 30.0 mL of krypton gas, Kr, is at 756 mm Hg and 25.0°C. What is the new volume if the pressure is decreased to 325 mm Hg and the temperature is decreased to-12.5°C?arrow_forwardAt what temperature will a molecule of uranium hexafluoride, the densest gas known, have the same average speed as a molecule of the lightest gas, hydrogen, at 37C?arrow_forwardCalculate the densities (in grams per liter) of the following gases at 97C and 755 mm Hg. (b) sulfur dioxide (a) hydrogen chloride (c) butane (C4H10)arrow_forward
