Answer

26.72 g NaOH

Explanation

1. Understand Molality Formula Molality (m) is defined as moles of solute per kilogram of solvent. **Molality = \frac{\text{moles of solute}}{\text{kg of solvent}}**2. Convert Solvent Mass to Kilograms 232 g of water is equivalent to 0.232 kg.3. Calculate Moles of NaOH Required Using the molality formula:

. Therefore, moles of NaOH =

.4. Calculate Grams of NaOH Moles of NaOH =

. Grams of NaOH = moles

molar mass =
