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_(O2) gt N_(H2)`

B

`N_(O2) lt N_(H2)`

C

`N_(O2) = N_(H2)`

D

`N_(O2) + N_(H2) = 1 ` mole

Text Solution

Verified by Experts

The correct Answer is:
C
This is Avogadro.s hypothesis.
According to this, equal volumes of all gases contain equal no. of molecules under similar condition of temperature and pressure.
