When 171. g of benzamide (C₂H₂NO) are dissolved in 750. g of a certain mystery liquid X, the freezing point of the solution is 6.10 °℃ less than the freezing
point of pure X.
Calculate the mass of iron(III) nitrate (Fe(NO₂
(Fe(NO3)3) that must be dissolved in the same mass of X to produce the same depression in freezing point. The van't
Hoff factor i=3.64 for iron(III) nitrate in X.
Be sure your answer has a unit symbol, if necessary, and is rounded to the correct number of significant digits.
