MCQ

Which has minimum number of atoms of oxygen?

A
$10\, ml\, H_2O(l)$
B
$0.1\, mol$ of $V_2O_5(s)$
C
$12\, gm\, O_3(g)$
✓
$12.04\times10^{22}$ molecules of $CO_2$

✓

Answer

Correct option: D.

$12.04\times10^{22}$ molecules of $CO_2$

d
$1$ molecule of $\mathrm{CO}_{2}$ contains $2$ atoms $12.04 \times 10^{22}$ molecule contain

${=12.04 \times 10^{22} \times 2} $

${=24.08 \times 10^{22} \text { atoms of oxygen }}$
