Solution

The correct option is D 0.5
One mole of substance contains $6.023 \times 10^{23}$ particles.
In $C O_{2}$ , Molecular mass $= 44 g = 1 m o l e$
Given : $3.0115 \times 10^{23}$ particles present in $C O_{2}$
$∴$ Number of moles in $3, 0115 \times 10^{23}$ particles of $C O_{2},$
$= \frac{3.0115 \times 10^{23}}{6.023 \times 10^{23}} = 0.5$
