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