Air is a mixture of many gases. However, in calculating its “molar mass” we need consider only the three major components: nitrogen, oxygen, and argon. Given that one mole of air at sea level is made up of 78.08 percent nitrogen, 20.95 percent oxygen, and 0.97 percent argon, what is the molar mass of air?

QUESTION:
Air is a mixture of many gases. However, in calculating its “molar mass” we need consider only the three major components: nitrogen, oxygen, and argon. Given that one mole of air at sea level is made up of 78.08 percent nitrogen, 20.95 percent oxygen, and 0.97 percent argon, what is the molar mass of air?
ANSWER:Step 1 of 3
The goal of the problem is to calculate the molar mass of air.
Given:
Mass percent of nitrogen =78.08 %
Mass percent of oxygen = 20.95 %
Mass percent of argon = 0.97 %
