Calculate molality of `2.5g` of ethanoic acid `(CH_(3)COOH)` in `75 g` of benzene.

Explanation

To calculate the molality of 2.5 g of ethanoic acid (CH₃COOH) in 75 g of benzene, we will follow these steps:

### Step 1: Calculate the number of moles of ethanoic acid.
The formula to calculate the number of moles is:

\[ \text{Number of moles} = \frac{\text{mass of solute (g)}}{\text{molar mass of solute (g/mol)}} \]
