Answer

14

Reason —

Given,
The relative molecular mass(RMM) of carbon monoxide = 28.
The vapour density of carbon monoxide = ?

Vapour density =  Relative molecular mass2\dfrac{\text{ Relative molecular mass}}{2}

Vapour density = 282\dfrac{28}{2} = 14

Hence, the vapour density of carbon monoxide is 14.
