Question

To what volume, in mL, must 50.0 mL of 3.50 M $H_{2}S{O}_4$ be diluted in order to make 2 M $H_{2}S{O}_4$?

• A. $25$
• B. $60.1$
• C. $87.5$
• D. $93.2$
• E. $101$

Answer 1

The correct option is C $87.5$

No. of moles should be same in both cases so

$M_1{V}_1$$=$$M_2{V}_2$

or $V_2$$=$$M_1{V}_1/M_2$$=$$3.5\times 50/2$$=$$87.5ml$
