Unformatted text preview: 4 was decomposed? The vapor pressure of water at 19.25 °C is 16.7 torr. Question 5 Calculate the density of silane (SiH 4 ) gas at 32.5 °C at a pressure of 1327 torr. Question 6 A sample of helium gas at a pressure of 855 torr occupies a volume of 328 mL. If the pressure changes to 1.22 atm, what volume will the gas occupy? Question 7 Convert 2.340 lb in1 h2 to atm (h = hours, in = inches). Question 8 A gas cylinder contains 22 % nitrogen, 31 % oxygen, 18 % neon, and 29 % hydrogen. If the total pressure in the cylinder is 1.21 x 10 5 Pa, what are the partial pressures of each of these gasses? Question 9 Calculate the rate of effusion of methane to that of chlorine. Question 10 A sample of argon gas occupies a volume of 310.5 mL at 19.5 °C. If the temperature increases to 66.5 °C, what volume will the argon occupy?...
