at 26 C the sollubility of soduim chloride is 36g/100ml solution. how would the solution be at 10 g of soduim chloride in 100 mlL of solution at room temp?

calculate the freezing point of a 2 molal solution of a nonelectrolyte glucose. feezing point constant for water being 1.86 C/molal

Solution

36 g glucose dissolved in 100 ml water....

moles glucose = mass / mw = 36 g / 180 g/mole = 2 moles
m = moles solute / kg solvent = .2 moles / 1 kg = 2 molal
i = 1
