Find molality of a solution
Web1 Answer. Sorted by: 1. The boiling point elevation fomula assumes that all particles are equal, only the number of particles in the solution matters. So I would use: m = (0.2 + (3) (0.8)) (molality of M g C l X 2) + (0.2 + (2) (0.8)) (molality of N a C l) To find molality of M g C l X 2 and molality of N a C l, consider a 1kg sample of the ... WebAug 27, 2024 · The formula for molality is m = moles of solute / kilograms of solvent. In problem solving involving molality, we sometimes need to use additional formulas to get to the final answer. One formula we need to be aware of is the formula for density, which is d = m / v, where d is density, m is mass and v is volume.
