100 mL of `O_(2) and H_(2)` are kept at same temperature and pressure. What is true about their number of molecules ?

A

`N_(O_(2)) gt N_(H_(2))`

B

`N_(O_(2)) lt N_(H_(2))`

C

`N_(O_(2))=N_(H_(2))`

D

`N_(O_(2))+N_(H_(2))=1` mole

Text Solution

Verified by Experts

The correct Answer is:
C
This is Avogardo's hypothesis.
According to this, equal volume of all gases contain equal no. of molecules under similar condition of temperature anf pressure.
