Answer:

0.81mole

Explanation:

Given:

Volume of carbon monoxide  = 18dm³

Unknown

Number of moles of carbon monoxide  = ?

Solution:

To solve this problem;

           1 mole of any gas at rtp occupies a volume of 22.4dm³  

So;

           x mole of carbon monoxide will occupy a volume of 18dm³ at rtp

        22.4x  = 18

                x  = \frac{18}{22.4}   = 0.81mole
