A) 16 g of \[{{O}_{2}}\]and 14 g of \[{{N}_{2}}\]
B) 8 g of \[{{O}_{2}}\]and 22 g of \[C{{O}_{2}}\]
C) 28 g of \[{{N}_{2}}\]and 22 g of \[C{{O}_{2}}\]
D) 32 g of \[{{O}_{2}}\]and 32 g of \[{{N}_{2}}\]
Correct Answer: A
Solution :
16g \[{{O}_{2}}\]has no. of moles \[=\frac{16}{32}=\frac{1}{2}\] 14g \[{{N}_{2}}\] has no. of moles \[=\frac{14}{28}=\frac{1}{2}\] No. of moles are same, so no. of molecules are same.
