WebHow to Convert Grams to Moles. The mole (abbreviated mol) is the SI unit of amount of substance. One mole is defined to contain exactly 6.02214076 x 10 23 elementary entities (atoms, molecules, ions or electrons). This number (known as Avogadro number) was chosen so that the mass of one mole of a chemical compound in grams is numerically … WebDec 2, 2024 · The equation can be rearranged to solve for moles: n = RT/PV. The units of the gas constant are designed to cancel out the units of the other variables. For example, determine the number of moles in 2.4 liters of O 2 at 300 K and 1.5 atm. Plugging in the variables yields: n = (0.0821 x 300)/ (1.5 x 2) = 24.63/3.6 = 6.842 moles of O 2 Part 4
