Question
The boiling point of chloroform (CHCl₃) is 61.70 °C at 1 atmosphere. A nonvolatile, nonelectrolyte that dissolves in chloroform is aspirin.

**Question:**

How many grams of aspirin, C₉H₈O₄ (180.1 g/mol), must be dissolved in 204.0 grams of chloroform to raise the boiling point by 0.350 °C? Refer to the table for the necessary boiling or freezing point constant.

**Table of Solvents and Properties:**

| Solvent      | Formula          | \(K_b\) (°C/m) | \(K_f\) (°C/m) |
|--------------|------------------|----------------|----------------|
| Water        | H₂O              | 0.512          | 1.86           |
| Ethanol      | CH₃CH₂OH         | 1.22           | 1.99           |
| Chloroform   | CHCl₃            | 3.67           | —              |
| Benzene      | C₆H₆             | 2.53           | 5.12           |
| Diethyl ether| CH₃CH₂OCH₂CH₃    | 2.02           | —              |

**Answer:**

Mass = [Text Box] g

The table lists solvents with their respective chemical formulas, boiling point elevation constants (\(K_b\)), and freezing point depression constants (\(K_f\)). This data is necessary to determine how much aspirin needs to be dissolved to achieve the desired change in boiling point.
