Nitrate 2 , Hydrogen Oxygen , and Carbon Oxide
Following the law of conservation of mass, the mass percent of hydrogen in the resulting compound is 14.4%(wt/wt). This is assuming that all of the carbon reacts with all of the hydrogen. The solution is as follows:
mass % = mass hydrogen*100/total mass = 28.8*100/(28.8+171.2) = 14.4%
10-7.5=2.5, 2.5/2=1.25, 7.5+1.25=8.75
