How many grams of glycerol must be added to 430.g of water to lower the vapor pressure 1.40 mm Hg at 25°C? The vapor pressure of water at 25 °C is 23.8mm Hg, and the molar mass of glycerol is 92.09 g/mol.

In order to calculate the amount of heat transferred you must know the __ and specific heat of the material, as well as the change in temperature. a. volume b. density c. mass d. enthalpy
