1 atm is how many mmhg


Ideal Gas Law: Problem Set #1 Problem #1: Determine the volume of occupied by 2. 34 grams of carbon dioxide gas at STP. Solution: 1) Rearrange PV = nRT to this: V = nRT / P 2) Substitute: V = [ (2. 34 g / 44. 0 g mol¯ 1 ) (0. 08206 L atm mol¯ 1 K¯ 1 ) (273. 0 K) ] / 1. 00 atm V = 1. 19 L (to three significant figures) Problem #2: A sample of argon gas at STP occupies 56. 2 liters. Determine the number of moles of argon and the mass in the sample. Solution: 1) Rearrange PV = nRT to this: n = PV / RT 2) Substitute: n = [ (1.
