    A gas is found to have a formula \[{{[CO]}_{x}}\]. If its vapour density is 70, the value of x is

    A)  2.5                                        

    B)  3

    C)  5                                            

    D)  6

    Correct Answer: C

    Solution :

                     Molecular weight \[=2\times \] vapour density                                 \[=2\times 70=140\] \[\therefore \]  \[{{(CO)}_{x}}=140\] or            (12 + 16) x = 140 or            28x = 140                 x = 5
