WebDec 26, 2024 · Molality is concentration expressed in terms of moles per unit mass. Relation between Molarity (M) and Molality (m) is given by. m = 1000M 1000p−M M 1 m = 1000 M 1000 p − M M 1. Where. ρ is the density of the solution (mg/mL). M1 is the molecular weight of the solute. Table of Content. WebFormation of term molality is in analogy to molarity which is that the molarity of a solution. During this chapter, we'll discuss the molality formula. ... 5% (w/w) glucose solution is given .Find the molality of solution (density = 1.5gm/cc). Solution: Molar mass of glucose = 6 × 12 + 12 × 1 + 6 × 16 = 180 g mol-1. 5% (w/w) glucose solution ...
