### Calculating and Using the van't Hoff Factor for Electrolytes

**Problem Statement:**

When 378. g of benzamide \((C_7H_7NO)\) are dissolved in 1300. g of a certain mystery liquid \(X\), the freezing point of the solution is 9.00 °C less than the freezing point of pure \(X\).

Calculate the mass of iron(III) nitrate \((Fe(NO_3)_3)\) that must be dissolved in the same mass of \(X\) to produce the same depression in freezing point. The van't Hoff factor \(i = 3.76\) for iron(III) nitrate in \(X\).

**Instructions:**

Be sure your answer has a unit symbol, if necessary, and round your answer to 3 significant digits.

**Input Field:**

- A blank input field is provided for entering the calculated mass.

**Additional Notation:**

- There is an on-screen keypad with options to input different mathematical symbols and numbers to facilitate the calculation process.
