okay its like this...i ve worked it out and i came up with this solution...
Now they have given the mass of Hydrogen and *other atoms*= when u add both and divide by the Avagrado constant, You get the mass (my bad i forgot it :P)
$$[2\times 10^{-23} + 16 \times 10^{-23} = 1.8  \times 10^{-22}  \times 6.022 \times 10^{23}$$

= Mass of the (Hydrogen + other substance)
=108 (approximately) 

ADD it with 6 carbon atoms ------> 180 :)

not divide it should be multiply
