calculate the molality of 32% solution of ethyl alcohol in water

Dear Student,32 % solution of ethanol in water means 32 g of ethanol in 100 g of solution.Molality =Moles of soluteMass of solvent in KgMass of solvent = 100 -32 =68gMoles of solute =MassMolar mass = 3246=0.695 MoleMolality =0.69568×10-3 =10.2 molalRegards

molality=0.32
molality=mass of solute/molar mass of solute x mass of solvent
in this case...m=32/32+68
so,m=32/100
=0.32
