A mixture of 0.242 g of H2, 1.12 g of N2, and 0.839 g of Ar is stored in a closed container at STP. Find the volume (in L) of the container, assuming that the gases exhibit ideal behavior.
Question
A mixture of 0.242 g of H2, 1.12 g of N2, and 0.839 g of Ar is stored in a closed container at STP. Find the volume (in L) of the container, assuming that the gases exhibit ideal behavior.
Solution
Sure, here are the steps to solve this problem:
-
First, we need to convert the mass of each gas to moles. We do this by dividing the mass of each gas by its molar mass. The molar mass of H2 is approximately 2 g/mol, the molar mass of N2 is approximately 28 g/mol, and the molar mass of Ar is approximately 40 g/mol.
Moles of H2 = 0.242 g / 2 g/mol = 0.121 mol Moles of N2 = 1.12 g / 28 g/mol = 0.04 mol Moles of Ar = 0.839 g / 40 g/mol = 0.021 mol
-
Next, we add up the moles of each gas to find the total number of moles in the container.
Total moles = 0.121 mol + 0.04 mol + 0.021 mol = 0.182 mol
-
At standard temperature and pressure (STP), one mole of any gas occupies a volume of 22.4 liters. So, we multiply the total number of moles by 22.4 L/mol to find the volume of the container.
Volume = 0.182 mol * 22.4 L/mol = 4.07 L
So, the volume of the container is approximately 4.07 liters.
