How many molecules are in 0.25 moles?
Solution : We know that : <br> `1` mole of oxygen contains ` = 6.022 xx 10^(23)` molecules <br> So, `0.25` moles of oxygen contains `= 6.022 xx 10^(23) xx 0.25` <br> `= 1.505 xx 10^(23)` molecules <br> Thus, `0.25` mole of oxygen contains `1.505 xx 10^(23)` molecules.
