22. (6 points) A sample of methane, CH4, occupies a volume of 202.0 mL at 25°C and exerts a pressure of 455.0 mmHg. If the volume of the gas is allowed to expand to 390.0 mL at 345 K, what will be the pressure of the gas? =.2024. PV=nRT 243 2 455.4 Hy J 202 2 7 0.08206 2² 202.0x 202.00 (4.55,0)(2024) = n(0.08206) (298) 91.9= 24.5 n 24.55 23. (5 points) What is the density of 731 mm Hg of O2 gas at 268 K? n=3.75mmity 7311 =1962 atm x 268 k = 257,816121 760 1258
