What is the number of O-atoms present in 44.8 L of ozone gas at STP?

Text Solution

Verified by Experts

At STP, number of molecules present in 22.4 L of ozone gas=`6.022xx10^(23)`
`therefore`Number of molecules present in 44.8 L of ozone gas at
`STP=(6.022xx10^(23)xx44.8)/(22.4)=2xx6.022xx10^(23)`
`therefore`Number of oxygen atoms present in the given volume of ozone gas`=3xx2xx6.022xx10^(23)=3.6132xx10^(24)`
[Since each molecule of ozone contains 3O-atoms].
