of solution of "10 volume" strength contains of . Find (nearest integer). — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
$1 \text{ liter}$ of $H_2O_2$ solution of "10 volume" strength contains $x \text{ grams}$ of $H_2O_2$. Find $x$ (nearest integer).
Answer: 30
💡 Solution & Explanation
$\text{Molarity} = 10 / 11.2 = 0.892 \text{ M}$. <br>$\text{Mass} = \text{Molarity} \times \text{MW} = 0.892 \times 34 = 30.3 \text{ g} \approx 30 \text{ g}$. [7, 29]
