WebJan 3, 2024 · In other words, molality is the number of moles of solute (dissolved material) per kilogram of solvent (where the solute is dissolved in). It is possible to recalculate from … WebThe molarity of H 2SO 4 is 18 M. Hence, 1 L of H 2SO 4 corresponds to 18 moles of H 2SO 4. The density of H 2SO 4 is 1.8 g/mL. Thus 1 L of H 2SO 4 corresponds to 1800 g or 1.8 kg. Out of this 18×98=1.764kg corresponds to H 2SO 4. Hence, the mass of water is 1.8kg−1.764kg=0.036kg. Hence, the molality of the solution is 0.03618 =500m.
WebThe molality of the solution is (2.4 mol C3H5(OH)3, 0.425 kg H2O)= 5.7 m 9. Concentrated HCl is 12.0M and has a density of 1.18 g/cm3. (a) The molality of the solution: Molality is defined as moles HCl/kg solvent, so begin by deciding the mass of 1 L, and the mass of water in that 1L. Since the density = 1.18g/mL, then 1 L (1000 mL) will have a
