D

`54 g` of nitrogen pentoxide

Text Solution

Verified by Experts

The correct Answer is:
A
The number of molecules in `36 g` of water is
`(36)/(18) N = 2 N`
The number of molecules in `28 g` of `CO` is
`(28)/(28) N = N`
The number of molecules in `46 g` of `C_(2) H_(5) OH` is
`(46)/(46) N = N`
The number of molecules in `54 g` of `N_(2)O_(5)` is
`(54)/(108) N = (1)/(2) N`
