A solution is prepared by mixing 100 g of an unknown calcium salt (CaX2) into 270.3 ml of water. If the vapor pressure of pure water is 23.8 mmHg at 25 degrees C and the vapor pressure of the mixture is 21.6 mmHg, determine the molar mass of the calcium salt. If the vapor pressure of the mixture was instead found to be 22.4 mmHg what was the percent disassociation of the CaX2?
