When 70.8g of urea CH4N2O are dissolved in 1350.g of a certain mystery liquid X, the freezing point of the solution is 7.70°C less than the freezing point of pure X.Calculate the mass of iron(III) chloride that must be dissolved in the same mass of X to produce the same depression in freezing point. The van't Hoff factor =i3.40 for iron(III) chloride in X.Be sure your answer has a unit symbol, if necessary, and round your answer to 3 significant digits.
