1. Understand the formula for molality: Molality (m)=Weight of solute (g)×1000Molecular weight (g/mol)×Weight of solvent (g) 2. Determine the weight of solute and solvent: - In a 100 g solution, the weight of solute (sulfuric acid) = 13 g - The weight of solvent (water) = 10...
Molality Formula Since it’s a ratio, you can calculate molality using the following formula: molality (m) =moles of solute/kilograms of solvent Thus, the molalitymis equal to the amount of substance of solute in moles divided by themassof solvent in kilograms. ...

- Mass of water in kilograms = 13.5 g / 1000 = 0.0135 kg. Now we can calculate the molality (m) using the formula: - Molality (m) = Moles of solute / Mass of solvent in kg - Moles of solute (methanol) = 0.25 moles. - Molality (m) = 0.25 moles / 0.0135 kg ≈ 18.52 mol/kg...
Molar mass is the sum of all of the atomic masses in a formula. More information and molar mass calculator.Mole (mol) is the basic unit of measurement in chemistry. By definition, in modern chemistry, one mole represents the number of carbon atoms in exactly 12 grams of carbon 12 (C12)...
