Question

0.833 mol of carbohydrate of empirical formula CH2O gas 10gm of hydrogen. calculate the molecular formula of carbohydrate​

Answer 1

Answer:

It is given that 0.0833 moles of carbohydrate contains 1 g hydrogen. This means that 2n x 0.0833 moles of hydrogen contain 1 g of hydrogen. solving the equation, we get, n = 6. Thus, the molecular formula of the carbohydrate is C_6H_12O_6 , which is the molecular formula of glucose

Answer 2

Answer:

hope i will help you

Explanation:

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
