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

Answer»

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

Solution :ACCORDING to Avogadro.s law, equal volumes of gases contain equal number of molecules under similar CONDITIONS of temperature and pressure.
