x L of nitrogen at N.T.P. contains 3.0xx10^22molecules. The number of molecules in x/2ozone at N.T.P. will be

Answer»

`3.0 xx 10^22 `
`1.5 xx 10^22`
`1.5 xx 10^21`
`1.5 xx 10^20`

Solution :Equal volume of gases at N.T.P. CONTAIN equal NUMBER of MOLECULES
`x/2` L of ozone at NTP will contain
` = (3.0 xx 10^22)/(2) = 1.5 xx 10^22`
