When 314g of glycine are dissolved in 1350.g of a certain mystery liquid X, the freezing point of the solution is 3.30 degrees celsius less than the freezing point of pure x.

Calculate the mass of iron(III) nitrate that must be dissolved in the same mass of x to produce the same depression in freezing point. The van't Hoff factor is 3.12 for iron(III) nitrate in X.
