The formula shows that the compound contains 8 hydrogen atoms per molecule, of which the gram molecular mass is 46.07. Each hydrogen atom has a gram Atomic Mass of 1.00794. Therefore, the percent by mass of hydrogen in the compound is 100[8(1.00794)/46.07] or 17.50 %, to the justified number of significant digits. (The value "8" is exact.)

What is the precent composition of hydrogen in water?
The formula of water is H2O. The gram atomic mass of hydrogen is 1.008 and the gram atomic mass of oxygen is 15.999. Therefore, the mass percent composition of hydrogen in water is 100{(2)(1.008)/[(2)(1.008) + 15.999] or 11.19 %.The percent composition of hydrogen in water is: 11,19 %.
What happen when benzene reacts with ch3cocl in presence oa hydrous alcl3?
This is an example of a Friedel-Crafts acylation. One hydrogen from the benzene is replaced by the acetyl portion of the acetyl chloride and the hydrogen and chloride from the benzene and acetyl chloride respectively combine to form HCl. Please see the link.
