Question

Out of 1.0 g dioxygen 1.0 g (atomic) oxygen and 1.0 g ozone the maximum number of oxygen atoms are contained in

• A. 1.0 g of atomic oxygen
• B. 1.0 g of ozone
• C. 1.0 g of oxygen gas
• D. All contain same number of atoms

Answer 1

Answer: (D)

All contain same number of atoms

Answer 2

Since mass of oxygen is same. Therefore, the number of gm-atom and also the number of atoms will be same in all the samples i.e., Atoms of oxygen $=\frac{1\times2}{32}$ in $O_{2}$ $=\frac{1}{16}$ in atomic oxygen $=\frac{1 \times3}{48}$ in $O_{3}$
