What is the mass percent of hydrogen in hexanal?

Answer : The mass percentage of hydrogen in hexanal is, 12 %

Explanation: Given,

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

Molar mass of O = 16 g/mole

First we have to calculate the molar mass of hexanal.

Molar mass of hexanal =

Now we have to calculate the mass of carbon.

As we now that there are 6 number of carbon atoms, 12 number of hydrogen atoms and 1 number of oxygen atoms.

The mass of hydrogen =

Now we have to calculate the mass percentage of hydrogen in hexanal.

Formula used :

Now put all the given values in this formula, we get:

Therefore, the mass percentage of hydrogen in hexanal is, 12 %

the answer to your question is c.
