WebWhat is the molecular weight of this moist air? Answer. The molecular weight Ma of moist air is given by where Ma,dry =28.96x10-3 kg mol-1 is the molecular weight of dry air … WebFeb 22, 2024 · Distributions of the Value of Molecular Speed. In the mid-19 th century, James Maxwell and Ludwig Boltzmann derived an equation for the distribution of molecular speeds in a gas. Graphing this equation gives us the Maxwell-Boltzmann distribution of speeds. The Maxwell-Boltzmann speed distribution curve for N 2 at 25ºC is shown below.. … WebThe average molar mass of mixtures can be calculated from the mole fractions xi of the components and their molar masses Mi : It can also be calculated from the mass fractions wi of the components: As an example, the average molar mass of dry air is 28.97 g/mol.
