Vedclass · Answer

(B) The molar mass of ozone $(O_3)$ is $3 	imes 16 = 48 \ g/mol$. Number of moles of $O_3 = \frac{8 \ g}{48 \ g/mol} = \frac{1}{6} \ mol$. Each molecule of $O_3$ contains $3$ oxygen atoms. Total number of oxygen atoms = $(	ext{Number of moles of } O_3) 	imes 3 	imes N_A$. Total number of oxygen atoms = $\frac{1}{6} 	imes 3 	imes N_A = \frac{1}{2} N_A = \frac{6.02 	imes 10^{23}}{2}$.
