Question

At a certain temperature and pressure, 1 L of CO2 gas weighs 1.05 g. What is the mass of 1 L of N2 gas at the same temperature and pressure? mass of 1 L of N2:

Answer 1

(1.05g CO₂) * (1 mol CO₂ / 44.0g CO₂) = 0.02386 mol CO₂. The same volume of N₂ gas would be the same number of moles, so (0.02386 mol N₂) * (28.0g N₂ / 1 mol N₂) = 0.668g N₂.
