1) If a solution is prepared by mixing 15.7 mL of CH3CH2OH (d = 0.792 g/mL) and 457 mL of CH3CH2CH2OH (d = 0.911 g/mL) what is the concentration in molality m?

2) What would be the vapor pressure if 55.6 g of a sugar (C6H12O6) is dissolved in 440.0 mL of water (d = 1.00 g/mL). The vapor pressure of water at this temperature is 23.9 torr.

3) 13.2 mg of an unknown non-volatile compound is dissolved in 403 mL of water at 25C. If the solution has an osmotic pressure of 10.44 torr, what is the molar mass of the compound?
