dNo. of the oxygen atoms in 22 g of

<br> Molar mass of

<br> 44g of

represent = 1 mol <br> 22g of

represent

<br> Now, 1 mole of

contain oxygen atoms

<br>

moles of

contain oxygen atoms

atoms <br> Step II. Weight of carbon monoxide <br> Molar mass of

g By definitioon,

atoms (or 1 mole oxygen atoms) are present in CO = 28 g.
