68. How many moles of gas must be forced into a 4.8-L fire to give it a gauge pressure of 32.4 psi at 25 °C? The gauge is relative to atmospheric pressure. Assume that pressure atmospheric pressure is 14.7 psi so that the total pressure in the tire is 47.1 psi. 70. An experiment shows that a 113-mL gas sample has a mass of 0.171 g at a pressure of 721 mm Hg and a temperature of 32 °C. What is the molar mass of the gas? 72. A sample of gas has a mass of 0.555 g. Its volume is 117 ml at a temperature of 85 °C and a pressure of 753 mm Hg. Find the molar mass of the gas. vih dupe A 74. A m0
