M eq of NaOH = Volume × Molarity =250 × 0.1=25 Let's now find how many g of NaOH will be needed to prepare 250 mL of 0.1 M solution (w/40) × 1000=25 w=1 g.

Q. How many $g$ of $N a O H$ will be needed to prepare $250 m L$ of $0.1 M$ solution?

1 g

10 g

4 g

6 g

$M_{e q}$ of $N a O H =$ Volume $\times$ Molarity $= 250 \times 0.1 = 25$
Let's now find how many g of $N a O H$ will be needed to prepare $250 m L$ of $0.1 M$ solution $\frac{w}{40} \times 1000 = 25$
$w = 1 g .$
