WebFeb 17, 2024 · Molality is used because mass doesn't depend on temperature (in a closed system at least). Compared to molarity (mass per volume) it is thus more accurate because it's temperature invariant. But how can a solvent (e.g water) have mass in the first place? Since solvents are fluids which have only volume? WebActivity depends on temperature, pressure and composition of the mixture, among other things. ... these values would all be unity. The deviations tend to become larger with …

WebSolution. Molarity is a function of volume which is a function of temperature as volume changes with temperature. But molality depends on the mass of solute and solvent which are independent of temperature. and molality is number of moles of solute particles dissolved in per kg mass of solvent. Thus, option D is correct.

WebMolarity = volume of solution (in L)number of moles of soluete. Number of moles are independent of temperature but volume increases with increase in temperature. Solve … 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.
