Which has maximum number of molecules among the following ?

Options

A. 44 g of `CO_(2)`
B. 48 g of `O_(3)`
C. 8 g of `H_(2)`
D. 64 g of `SO_(2)`

Answer

C

Explanation

No. of moles of `CO_(2)=((44g))/(("44 g mol"^(-1)))=1` mol
No. of moles of `O_(3)=((48g))/(("48 g mol"^(-1)))=1` mol
No. of moles of `H_(2)=(8g)/(("2g mol"^(-1)))=4` mol
No. of moles of `SO_(2)=((64g))/(("64g mol"^(-1)))=1` mol
`:.` 4 moles or 8g of `H_(2)` have max. no of molecules.
