A flask P contains `0.5` mole of oxygen gas. Another flask `Q` contains `0.4` mole of ozone gas. Which of the two flasks contains greater number of oxygen atoms ?

Text Solution

Verified by Experts

`"1 molecule of oxygen"(O_(2))="2 atoms of oxygen"`
`"1 molecule of oxygen"(O_(3))="3 atoms of oxygen"`
In flask P: `"1 molecule of oxygen gas"=6.022xx10^(23)"molecules"`
`"0.5 molecule of oxygen gas"=6.022xx10^(23)xx0.5"molecules"`
In flask Q: `"1 molecule of oxygen gas"=6.022xx10^(23)"molecules"`
`"0.4 molecule of oxygen gas"=6.022xx10^(23)xx0.4"molecules"`
`=6.022xx10^(23)xx0.4xx3"atoms"=7.23xx10^(23)"atoms"`
