Question

What will be the mass of a 0.500m solution of sodium acetate in water containing 0.5 Kg sodium acetate?

Open in App

Solution

Mass of sodium acetate $= 0.5$
$M o l a l i t y = \frac{M o l e s o f s o l u t e}{M a s s o f s o l v e n t (k g)}$
$⟹ 0.5 = \frac{0.5}{M_{H_{2} O} (k g)}$
$⟹ M_{H_{2} O} = 1000$ $g m$
Mass of $C H_{3} C O O N a = 82 \times 0.5 = 41$ $g m$
Total mass of solution $= 1041$ $g m$
