\[\mathrm{\dfrac{1\: mol\: Al}{26.98\: g\: Al}\quad and \quad \dfrac{26.98\: g\: Al}{1\: mol\: Al}} \nonumber\] The first conversion factor can be used to convert from mass to moles, and the second converts from moles to mass.
10 Αυγ 2022 · Perform conversions between mass and moles of a substance. Convert from mass or moles of one substance to mass or moles of another substance in a chemical reaction. Use a balanced chemical equation to determine molar relationships between substances.
11 Μαΐ 2023 · We use the molar mass (mass of one mole) of the substance to convert between mass and moles. When writing calculations, we denote the molar mass of a substance by an upper case “M” (e.g. M (Ne) means “the molar mass of neon”). As always, “n” stands for the number of moles and “m” indicates the mass of a substance.
7 Αυγ 2022 · mol = g x mol/g. Start with the number of grams and the chemical formula. Find the molar mass of the substance. Divide the mass by the molar mass for an answer in moles. For example, find the number of moles in 25.0 grams of potassium permanganate (KMnO 4). Using a periodic table, look up the masses of the elements: K = 39.01; Mn = 54.94; O ...

There are three steps to converting grams of a substance to moles. Determine how many grams are given in the problem. Calculate the molar mass of the substance. Divide step one by step two. Make sure you have a periodic table and a calculator handy. The solution technique can also be expressed in the following ratio and proportion:
