CHEM 111 Lecture Notes - Molar Mass, Weather Balloon, Gas Constant
Document Summary
Please check to make sure all your grades are posted. Once p, v, t and n were all related, a constant was needed. T = 273. 15 k (or 0 c) n = 1 mole. Determination of r: (1 atm x 22. 4141 l) / (1 mol x 273. 15 k) Note units of (atm x l) / (mol x k) How r is used to relate the equation: A rigid plastic container holds 35. 0 g of ethylene gas at a pressure of 793 torr. 793 torr / 35 g = p2 / 30 g. A gas-filled weather balloon of v = 65. 0 l is released at sea level with p = 745 torr and t. = 25 c. the balloon"s maximum v = 835 l. will the balloon make it to a height where p = 0. 066 atm and t = -5 c: sure no problem (new v < 835 l, only just. (new v is exactly 835 l)
