3. 10. g of gaseous argon, molar mass = 40. g/mol. occupies 5.0 L at 22 °C, 1.2 atm. (a) What volume will be occupied by this same 10. g of Aroccupy at 0 °C, 760 mm Hg? (Hint: what's special about 0 °C, 760. mm Hg?) Pivo = P2 V2 PViT PiViT2, V2 1.2 atm x 5.0L *2730 ???. 1.0 atm x 295k -= 5.6L (b) What volume would 10. g of argon occupy at 100. °C, 0.85 atm? 4. A sample of argon gas occupies 100. mL at 127 °C, 0.855 atm. The gas is cooled and compressed to a volume of 50 ml, at 33 °C. What pressure will it now exert? (Recall that in the combined gas law. pressure and volume can be in any units, so long as they are the same units for both pressures and the same units for both volumes.) 5. A sample of air is trapped in a cylinder that is fitted with a moveable piston. The volume of air is 500 ml at 22 (a) What volume will be occupied by this same 10. g of Aroccupy at 0 °C, 760, mm Hg? (Hint: what's special about 0 °C, 760. mm Hg?) 1.2 atm x 5.0Lx2736 TOT2 V2= = 5.6L TaTiPivi - P2V2 V, PV , V25 atm 295k (b) What volume would 10. g of argon occupy at 100. °C, 0.85 atm? A sample of argon gas occupies 100. mL at 127 °C, 0.855 atm. The gas is cooled and compressed to a volume of 50. ml, at 33 °C. What pressure will it now exert? (Recall that in the combined gas law, pressure and volume can be in any units, so long as they are the same units for both pressures and the same units for both volumes.) 5. m. A sample of air is trapped in a cylinder that is fitted with a moveable piston. The volume of air is 500 mL at 22°C..10 if the linder is placed in a cold bath at - 79°C, with no change in pressure, what volume will the gas now occupy?
