What will be the mass of a 0.500m solution of sodium acetate in water containing 0.15 mole of sodium acetate ?

Explanation

To find the mass of a 0.500 m solution of sodium acetate in water containing 0.15 moles of sodium acetate, we can follow these steps:

### Step 1: Understand the definition of molality (m)
Molality (m) is defined as the number of moles of solute per kilogram of solvent. The formula for molality is:
\[ m = \frac{n_b}{W_a} \]
where:
- \( n_b \) = number of moles of solute (sodium acetate in this case)
- \( W_a \) = mass of solvent in kilograms
