Answer to Question #159630 in General Chemistry for dale

Question

 A given aqueous solution has a density of x g/mL and y% solute by mass. Derive the mathematical equation relating the molarity of the solution, M, to the molality of the solution,m

Answer 1

Molarity= mol/ volume of solution (L)

Molality= mol/mass of solvent (kg)

n=m/Mr.

Molarity= Molality x mass of solvent/volume of solution.
