Question

At a given condition, 1 mol of $O_2$ occupies volume 30L. What is volume occupied by 1 equivalent of $O_2$ ?

• A. 7.5 L
• B. 6.2 L
• C. 5.7 L
• D. 8.2 L

Answer 1

Answer: (A)

7.5 L

As $1$ $mole$ of $O_2$ occupies $=3$ $L$
$⟹1$ $mole$ of $O_2$ weighs $30$ $grams$ that occupies $30$ $L$.
But $1$ equivalent of oxygen i.e., $8$ $gm$ occupies $\frac{30}{4}=7.5$ $L$
$7.5$ $L$ of volume is occupied.
