Now, compute the sum of products of number of atoms to the atomic weight: Molar mass (MgCl 2) = ∑ Count i * Weight i =. What is the molar mass (to the nearest tenth of a gram/mole) of each of the following KCl? What is the molar mass (to the nearest tenth of a gram/mole) of KCl, given of the following. Molecular Weight (MW) of K = 39.1 g/mol; MW of Cl= 35.5 g/mol.Jan 30, 2024 · 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. You can also use this molarity calculator to find the mass concentration or molar mass. Simply type in the remaining values and watch it do all the ... .
