0.0833 moles of a carbohydrate having empirical formula of CH2O contains one gram hydrogen, find molecular formula

Given EF= CH2O then mass=30

And carbohydrate(CH2O) contains 1gram hydrogen:

From EF it is obvious that 2 grams hydrogen present in 30 grams then 1grams hydrogen present in 15 grams corbohydrate.

Number of moles = Given mass/M.Mass

                              0.0833  =15/M.mass

Then M.mass=180

We Must needed 

Molecular Formula(MF) = n× Empirical Formula (EF)

MF=6(CH2O) = C6H12O6

Where n = Molecular mass/Empirical mass

             n= 180/30=6
