Question

0.0833mol of carbohydrate of epirical formula CH2O contain 1gram of hydrogen.thr molecular formula of the carbohydrate is​

Answer 1

Answer:

Let the molecular formula of the carbohydrate be equal to (CH

2

O)

n

In 1 mole of carbohydrate, there is 2n×1=2n g of hydrogen present

So, 0.0833 mole of carbohydrate there is 2n×0.0833 g of hydrogen which is equal to 1 g

2n×0.0833=1

∴n=6

So, the molecular formula of the carbohydrate will be (CH
