WebJun 26, 2024 · The molar weight of oxygen gas is 32 gram per mole. Based on that estimate for the weight of atmosphere, the total quantity of O2 in atmosphere is around 5*10^21/32 = 1.5625e+20 mole. you forgot to account for the fact oxygen only makes up ~23% of the atmosphere by mass. 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.
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.

WebJan 3, 2024 · Let's assume that you have 5 g of HCl in a 1.2 liter solution. Convert the expressions above to obtain a molarity formula. As mass / volume = molarity * molar mass, then mass / (volume * molar mass) = molarity. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M.
