WebJan 30, 2024 · Example – 01: 7.45 g of potassium chloride (KCl) was dissolved in 100 g of water. Calculate the molality of the solution. Given: mass of solute (KCl) = 7.45 g, mass of solvent (water) = 100 g = 0.1 kg. To Find: Molarity of solution =? Solution: Molecular mass of KCl = 39 g x 1 + 35.5 g x 1 = 74.5 g mol-1 WebJan 3, 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.
