are present in
<u>Explanation:</u>
It is known that each mole of an element is composed of avagadro's number of molecules. So if we need to determine, we need to divide the number of molecules with the avagadro's number.
So,
As here molecules of carbon di oxide is given. So the moles in it will be
No. of moles of carbon dioxide =
No. of moles = moles of carbon dioxide.
Thus,
of carbon dioxide are present in .
