In a mountainous location, the boiling point of pure water is found to be 95°C. How many grams of sodium chloride must be added to 9 kg of water to bring the boiling point back to 101°C? Assume that i = 2.

  • Chemistry -

    delta T = i*Kb*m
    Substitute and solve for m

    m = mols/Kg solvent
    Substitute and solve for mols

    mol = grams/molar mass. Substitute and solve for grams.
