Question

The molarity of a solution made by mixing 50ml of conc. $\mathrm { H } _ { 2 } \mathrm { SO } _ { 4 }$ (36N) with 50 ml of water is.

• A. 36 M
• B. 18 M
• C. 9 M
• D. 6 M

Answer 1

Answer: (C)

9 M

Answer 2

$N _ { 1 } V _ { 1 } = N _ { 2 } V _ { 2 }$, $36 \times 50 = N _ { 2 } \times 100$

$N _ { 2 } = \frac { 36 \times 50 } { 100 } = 18$; .
