Problem- A solution is prepared from 4.5709g of magnesium chloride and 43.246g of water. The vapor pressure of water above this solution is found to be 0.3630atm at 348.0 K. The vapor pressure of pure water at this temperature is 0.3804 atm
Find the value of the van't Hoff factor i for magnesium chloride in this solution.
Please demonstrate all work. Thank you in advance
