Question

0.15 molal solution of a substance boils at 373.23 K.Calculate molal elevation constant of water. (Givenboiling point of water = 373.15 K)​

Answer 1

Answer:

1 molar (M) aqueous solution is further concentrated than 1 molal (m) aqueous solution. Because 1 molar suspension contains 1 mole of solute in 1 liter of the solution which incorporates both solute and solvent. So, the mass of solvent (i.e. water) is less than 1000 grams.
