WebIdeal Gas Practice Problems. Problem 1: Under normal conditions (temperature 0 °C and atmospheric absolute pressure 100 kPa), the air density is 1.28 kg/m³. Determine the average molar mass of air. Solution: From the given air density we know that the mass of one cubic meter of air is 1.28 kg. Click the Reset button and enter the problem data into … WebMar 9, 2016 · For 1 mole of a gas, n=1. You are at ( 25o C) and 1 atm. So, solving PV=nRT for V, V=nRT/P = 24.453 liters. So now we know that we need 24.453 liters of gas to get one mole. That much gas will weigh: 24.453 liters *1.18 g/liter = 28.854 grams per mole. Adjusting to 3 significant figures: 28.9 grams per mole.
WebSubstitute this quotient for n in the ideal gas equation and solve for the molar mass. Describe the experimental data which would be needed to determine the molar mass of an unknown gas. Read the introduction to … WebYou can calculate the standard gas density fairly easily. Just take the mass of one mole of the gas and divide by molar volume. For example, using nitrogen, we would have: 28.014 g mol¯ 1 / 22.414 L mol¯ 1 = 1.250 g/L Remember, nitrogen is diatomic, N 2, not N. For water, we have: 18.015 g mol¯ 1 / 22.414 L mol¯ 1 = 0.8037 g/L
