WebUsing the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. WebPart A Assume air has an average molar mass of 28.8 grams per mole, and determine how many moles of air molecules there are in 8.95 L of air. (See Section 9.3 in the textbook for a review of this calculation.) Express your answer with the appropriate units.
