At 293.15 K, the partial vapor pressure of ethanol is 0.0587 atm, whereas a sample of magnesium chloride in ethanol solution at the same temperature has an ethanol vapor pressure of 4.23*10-2 atm. Assuming that all of the salt in solution is magnesium chloride, estimate the total ionic concentration (in molality). The density of ethanol is 0.79 g/mL at 293.15 K. Give your answer to the tenths position
