I think Im suppose to use this equation. Air - Molecular Weight and Composition - Dry air is a mixture of gases where the average molecular weight or molar mass can be calculated by adding the weight of each component. It is defined to be 112 of the mass of one atom of carbon-12 and in older works is also abbreviated as amu.
To find the molecular mass of a gas we can assume it behaves ideally and use the ideal gas law. Suppose for example that 250 g of a gas occupies a volume of 30 liters at 27 o C and a pressure of 40 atm. Molecular weight of gas Molecular weight often confused with molar mass The molecular weight unit in the SI system is kg.
MmixXNO2MNO2 XN2O4MN2O4 where I would just need to calculate the mole fractions and the molecular weight of the individual gases. We can use the Ideal Gas Law to calculate the number of moles of gas we have and then divide this number into the mass to get the molecular weight.
