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.)
