In
, there are 6 carbon atoms, 8 hydrogen atoms and 6 oxygen atoms.
To calculate the mass percent of element in a given compound, we use the formula:

Mass of hydrogen = 
Molar Mass of ascorbic acid =
Putting values in above equation, we get:

Hence, the mass percent of of hydrogen in ascorbic acid is 4.5 %.

(ANS1)— P4 + 5O2 ---> 2P2O5
(ANS2)— C3H8 + 5O2---> 3CO2 + 4H20
(ANS3)— Ca2Si + 4Cl2 ---> 2CaCl2 + SiCl4
