To dilute a HCl solution from 0.400 M to 0.100 M the final volume must be

sp2606 [1]

<u>Answer:</u>

<em>The final volume must be 400 mL.</em>

<em></em>

<u>Explanation:</u>

Let us assume the Initial volume as 100ml

Using dilution factor formula

$\\$M_{1} \times V_{1}=M_{2} \times V_{2}$\\\\$0.400 M \times 100 m l=0.100 M \times V_{2}$$

So,

$V_{2}=\frac{0.400 M \times 100 m l}{0.100 M}=400 m l$

Thus, the final volume must be 400 mL.
