Colligative Properties - Vapor Pressure I - Video Solution

What is the mole fraction of candle wax in a solution made by dissolving 10.0 g of solid candle wax (C22H46) in 40.0 g of the liquid solvent carbon tetrachloride (CCl4)?

At 20.°C, what is the vapor pressure of the solution specified in the preceding question? Candle wax is a nonvolatile, non-electrolyte. The vapor pressure of pure liquid CCl4 is 155 torr at 20.°C.
