WebAug 28, 2016 · Molarity is a temperature-dependent parameter. The volume of a solution increases with an increase in temperature diye to increase in intermolecular spaces and … WebMolality = (moles of solute)/ (kg of solvent) Notice molarity has a volume dependence. This means it has a density dependence. As you change the temperature and pressure, the density changes, the volume changes and hence the molarity changes.
WebMolarity of a solution does not depend upon temperature, whereas, molality depends on temperature. Reason Molarity and molality both depend only on the number of moles of solute particles.

WebConcentrations expressed in molality are used when studying properties of solutions related to vapor pressure and temperature changes. Molality is used because its value does not change with changes in temperature. The volume of a solution, on the other hand, is slightly dependent upon temperature.
WebStep 3. Determine the number of moles of compound in the solution from the molal concentration and the mass of solvent used to make the solution. Moles of solute = 0.63 mol solute 1.00 kg solvent × 0.0550 kg solvent = 0.035 mol. Moles of solute = 0.63 mol solute 1.00 kg solvent × 0.0550 kg solvent = 0.035 mol.
