Determine the melting point of an aqueous solution containing 115 mg of saccharin (C7H5O3NS)added to 1.00 mL of water (density of water=1.00 g/mL, Kt=1.86 C/m)

  • chemistry - ,

    mols saccharin = 0.115g/molar mass
    Solve for mols.

    m = mols/kg solvent
    m = mols/0.001
    solve for m

    delta T = Kf*m
    Solve for delta T and subtract from 0 C to find the melting point.
