• B. $1 L$ marketed solution contains $75 \,g$ of $H _2 O _2$.
• C. $1 L$ marketed solution contains $250\, g$ of $H _2 O _2$.
• D. $1 L$ marketed solution contains $25\, g$ of $H _2 O _2$.

Answer 1

Answer: (B)

$1 L$ marketed solution contains $75 \,g$ of $H _2 O _2$.

Answer 2

Volume =11.35×M
Strength
M=11.3525​M
g/L=25×34/11.35
=74.889
