The molar mass is the mass of one mole of substance, whether the substance is an element or a compound. A mole of substance is equal to Avogadro's number (6.023×10 23) of that substance. The molar mass has units of g/mol or kg/mol. When using the unit g/mol, the numerical value of the molar mass of a molecule is the same as its average mass in ...David Park. 4 years ago. First, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 g/mol. Since each mole is 126.737 grams, you multiply 3.5 mols by 126.737 grams, giving you 443.58 grams. 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. Molar Mass The molar mass of any substance is the …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”). ... Vitamin C is a covalent compound with the molecular formula C 6 H 8 O 6. The recommended …May 10, 2023 · Lastly, add the atomic masses of each element in the compound to get the molar mass of the compound. In this case, we add the atomic masses of calcium and chlorine to get the molar mass of calcium chloride: Molar mass of CaCl_2 = 40.08\text{ g/mol} + 70.90\text{ g/mol} = 110.98\text{ g/mol} You don't have to be a mathematician to follow this simple value statement formula.
