Answer to Question #260940 in General Chemistry for Renz

Question

a.) Find the mass of nonelectrolyte solute dissolved in 315 g water with a boiling point temperature of 100.45 ⁰C. The molar mass of solute is 46 g/mole   Kb = 0.52  ⁰C/m  and  Tb = 100 ⁰C (boiling point of pure solvent) 

b.) What is the % by mass of the solution? 

c.) Find the molarity of the solution if the density of the solution is  0.998 g/ml.

Answer 1

315+46= 371g

= 315/371×100

= 84.91%
