Molar Mass of Sulfur based on molality
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
