Hydrogen Question 7

Question 7 - 30 January - Shift 2

The strength of 50 volume solution of hydrogen peroxide is $g / L$ (Nearest integer).

Given:

Molar mass of $H_2 O_2$ is $34 g mol^{-1}$

Molar volume of gas at $STP=22.7 L$.

Show Answer

Answer: (150)

Solution:

Molarity $=\frac{50}{11.35}$

$\therefore$ Strength in $gm / L=\frac{50}{11.35} \times 34$
