The weight of carbon which contains the same number of atoms as those present in 15 g of oxygen is

The weight of carbon which contains the same number of atoms as those present in 15 g of oxygen is 11.25 g.
The molecular weight of O₂ = 32 g
Moles in 15g of oxygen =  $\frac{15}{32}$
As we know, 1 molecule of oxygen contains 2 oxygen atoms.
So, Several atoms in $\frac{15}{32}$ moles of oxygen = 12 g of carbon are equal to 1 atom.
So, the weight of 2 × $\frac{15}{32}$ atoms = $12 \times 2 \times \frac{15}{32}$
                                                        $=11.25g$
So, weight of carbon a that contains equal number of atoms as present in 15 g of oxygen is $11.25g$.
