In which of the following pairs, `10 g` of each have an equal number of molecules?

A

`N_(2)O` and `CO`

B

`N_(2)` and `C_(3)O_(2)`

C

`N_(2)` and `CO`

D

`N_(2)O` and `CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C, D
Equal number of moleucles are present when moles are same. For the same mass the molarcular weight has tobe same.
Hence, `Mw "of" N_(2) = Mw "of" CO = 28 g`
`Mw "of" N_(2) O = Mw "of" CO_(2) = 44 g`
