How many mols of N2 do you have ?
Well, 1 mol has mass of 2*14 = 28 grams
You have 0.234 grams so 0.234 grams * 1 mol/28 grams = 0.00836 mols of N2
P V = nRT
for the N2
10 kPascals * V = 0.00836 * R * 311
calculate V
then the partial pressures of the others are proportional to the number of mols of each
add those partial pressures to get total pressure.
A gas mixture being used to simulate the atmosphere of another planet consists of 342 mg
of methane, 169 mg of argon, and 234 mg of
nitrogen. The partial pressure of nitrogen at
311 K is 10 kPa. Calculate the total pressure
of the mixture.
Answer in units of kPa
and calculate the volume in units of L
