What is the vapor pressure in mmHg of a solution of 12.0 g NaF dissolved in 200.0 g water at 60 °C if NaF is a nonvolatile solute and completely dissolved in water? The vapor pressure of water at 60°C is 149 mmHg.

At 40.0 °C, the vapor pressures of ethyl acetate and chloroform, which are volatile and nonpolar hydrocarbons, are 188 mmHg and 360 mmHg, respectively. If a mixture of ethyl acetate and chloroform has a vapor pressure of 283 mmHg at 40.0 °C, what is X_chloroform?

A homogeneous mixture of ethyl alcohol (C₂H₅OH) and calcium acetate (C₄H₆CaO₄) is used to produce heat. If 15 torr of ethyl alcohol vapor pressure is needed, how much ethyl alcohol in grams should be mixed with 19 kg of calcium acetate at 30 °C? The vapor pressure of pure ethyl alcohol is 92 torr at 30 °C.

The vapor pressure of benzene at 20 °C is 75 torr while that of chloroform is 160 torr. Calculate the vapor pressure of the solution prepared by dissolving equal amounts (in moles) of the two liquids at 20 °C. Assume ideal behavior.
