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))gtN_(H_(2))`

B

`N_(O_(2))ltN_(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

According to Avogadro.s law, equal volumes of gases contain equal number of molecules under similar conditions of temperature and pressure.
