Question

2 L of 2.5 M $H_{2}S{O}_4$ solution is diluted to 15 L. Calculate the molarity of the resulting solution.

• A. 1.25 M
• B. 0.15 M
• C. 0.78 M
• D. 0.33 M

Answer 1

The correct option is D 0.33 M

As per the concept of dilution,
$M_1{V}_1=M_2{V}_2\Rightarrow 2.5\times 2=M_2\times 15$
$M_2=0.33$ M
