Question

0.1 mole of a carbohydrate with empirical formula CH2O contains 1 gm of hydrogen.What is the molecular formula​

Answer 1

Answer:

Let molecular formula for (Ch2O)n

In one mole of carbohydrate there is 2n gm of hydrogen present.

So, 0.1 mole of carbohydrate there is 2n/1 x 0.1 gm of hydrogen which is equal to 1 gm.

2n x o.1 = 1

molecular formula: C5h10O5.
