Answer 1

"(4) 4L Density of a gas at 300 K and 210 torr is 0.434 gL-1. What is its molar mass? (1) 14.78 g/mole (2) 73.43 g/mole (3) 38.68 g/mole (4) 43.28 g/mole multh o od of molecule at the. "

Answer 2

Answers

density (d) = MP / RT where M is molar mass, P is pressure, R is universal gas constant, T is temperature we're finding M, so: M = pRT / P Given: d = 0.434 P = 210 torr T = 300 R for torr = 62.363 M = (0.434 * 300 * 62.363) / 210 M = 38.67 Molar mass = 38.67 g/mole
