Molality (m) is defined as the number of moles of solute per kilogram of solvent. It is expressed in units of moles per kilogram (mol/kg) or molality (m). Molality is often used in situations where the volume of the solution changes with temperature, such as in thermodynamic calculations.
A 2 M solution of glucose (C6H12O6) has a density of 1.02 g/mL. What is the molality of the solution?
So, the molality of the solution is approximately 2.04 m.
First, we need to calculate the molecular weight of glucose:
