lauric acid: 3.950 g

benzoic acid: 0.392 g

freezing point lauric acid: 42.0 degrees Celscius

freezing point benzoic/lauric mixture: 39.0 degrees celsius

Kf for lauric acid: 4.40 degrees celsius*kg/mol

using the above information calculate the following:

molar mass for benzoic acid

the solutions freezing point depression

molality of benzoic acid in solution

the theoretical molar mass
