Vedclass · Answer

(D) Molar mass of ozone $(O_3)$ = $3 	imes 16 = 48 \ g/mol$. Number of moles of $O_3$ = $\frac{1.2 \ g}{48 \ g/mol} = 0.025 \ mol$. Number of molecules = $0.025 	imes 6.022 	imes 10^{23} \approx 1.5 	imes 10^{22}$ molecules. Since each molecule of $O_3$ contains $3$ atoms,the number of atoms = $3 	imes (1.5 	imes 10^{22}) = 4.5 	imes 10^{22}$ atoms.

The number of molecules and atoms present in $1.2 \ g$ of ozone $(O_3)$ are respectively:
