Assignment:
How many grams of naphthalene, C10H8, would you add to 49.5 g of benzene, C6H6 (l), to produce a solution that has the same freezing point as pure water? (Use the data from the table as needed.)
Molal Freezing Point Depression and Molal Boiling Point Elevation Constants:
Solvent Normal Freezing K(fr) Normal Boiling K(br)
Point,C C m^-1 Point, C C m^-1
Acetic acid 16.63 3.90 117.90 3.07
Benzene 5.53 5.12 80.10 2.53
Cyclohexane 6.55 20.0 80.74 2.79
Nitrobenzene 5.8 8.1 210.8 5.24
Water 0.00 1.86 100.00 0.512
