If you add 100 g of salt to 5 Kg of cooking water, how will it effect the boiling point? (molar mass of NaCl 58.5 g, Kbwater=0.51 degrees/m)

  • Chemistry -

    mols NaCl = 5000 g/molar mass NaCl.
    Solve for mols.

    molality = moles solute/kilograms solvent
    solve for molality

    Delta T = Kb*m
    solve for Delta T. The boiling point will be raised by the amount of Delta T.
    delta T = Kb*m
