WebMolality is a property of a solution and is defined as the number of moles of solute per kilogram of solvent. The SI unit for molality is mol/kg. A solution with a molality of 3 mol/kg is often described as "3 molal" or "3 m." However, following the SI system of units, mol/kg or a related SI unit is now preferred. WebThe solution to this problem involves two steps. Step One: convert grams to moles. Step Two: divide moles by kg of solvent to get molality. In the above problem, 58.44 grams/mol …
