Answer : The molality of a solution is, 0.387 mol/kg
Explanation : Given,
Mass of solute (glycine) = 100.7 g
Mass of solvent (water) = 3.466 kg
Molar mass of glycine = 75.1 g/mole
Formula used :

Now put all the given values in this formula, we get:


Thus, the molality of a solution is, 0.387 mol/kg
