    The density of air is 0.00130g/ml. The vapour density of air will be:

    A) 0.00065                        

    B) 0.65    

    C) 14.4816                        

    D) 14.56

    Correct Answer: D

    Solution :

    14.56 Molar mass of air = mass of 22400 cc at STP \[=0.00130\times 22400=29.12\] \[\operatorname{Vapour} density =\frac{Molar mass}{2}=\frac{29.12}{2}=14.56\]
