When 0.855 g of this solid was dissolved in 7.50 g of napthalene, the solution had a freezing point of 78.0° C. The pure solvent freezes at 80.0° C; its molal freezing point constant is 6.8° C/m. What is the molecular formula of the compound?

  • Chemistry -

    delta T = Kf*molality
    Solve for molality

    molality = moles/kg solvent
    Solve for moles.

    moles = grams/molar mass
    Solve for molar mass.
