What is the percent composition of hydrogen (h) in benzene (c6h6)?

Answer : The percent composition of hydrogen in benzene is, 7.69 %

Explanation: Given,

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

First we have to calculate the molar mass of benzene.

Molar mass of benzene =

Now we have to calculate the percent composition of hydrogen in benzene.

As we now that there are 6 number of carbon atoms and 6 number of hydrogen atoms.

The mass of hydrogen =

Formula used :

Now put all the given values in this formula, we get the percent composition of hydrogen in benzene.

Therefore, the percent composition of hydrogen in benzene is, 7.69 %
