    What would the molar mass of sulfur be based on the following data and information?
    2.07 grams of sulfur ( solute ) and 22.91 grams of naphthalene (solvent) was used. The Kf of naphthalene is 6.9 oC/m and delta T = Kf x m . The melting point of naphthalene was 80.50 oC and the melting point of the mixture was 78.0 o C.

    Relevant Formula:
    m ( molality ) = moles of solute / kg of solvent.

    dT = Kf x molality

    dT = 80.50 - 78.0 = 2.5 oC

    molality - moles of solute / kg of ...

    Solution Summary

    The molar mass of sulfur is calculated from molality.
