If the amount of helium produced by the large-scale liquefaction of air is 1.30 lbm per 100. tons of air, determine the mass, mole, and volume fractions of helium in air. Assume air is a mixture of ideal gases. 2. A mixture of air and water vapor at 20.0°C and 0.101 MPa has a relative humidity of 100.%. Using the information given in Example 12.2, determine
a. The molar composition.
b. The effective molecular mass.
c. The mass concentration.
d. The effective gas constant of the mixture, whose components are nitrogen, oxygen, water vapor, argon, and carbon dioxide.
