A 16.0 g sample of a compound known to contain 3 ion species is dissolved in 100. g of water. The boiling point of the solution is 103.1°C. What is the molar mass of the compound?

  • Chemistry -

    dT = i*Kb*m
    You know dT, i = 3, you know Kb, solve for m.
    Then m = mols/kg solvent. You know m and kg solvent, solve for mols.

    Then mols = grams/molar mass. You know mols and grams, solve for molar mass.
