BRAINLIEST!! IGNORE IF YOU DON'T KNOW Which compound contains the highest percentage of nitrogen by mass? Choose one and show your work. NH4NH2CO2
NH4NO2
N2O3
NH4Cl
NH2OH

NH4NO2.

Explanation:

Hello!

In this case, since the by-mass percent of any element (in this case nitrogen) is computed by:

Whereas n is the number of N in the compound, m the atomic mass of nitrogen (14.01 g/mol) and M the molar mass of the compound. Thus, down below we can find the molar mass of each compound and the by-mass percent of nitrogen:

NH4NH2CO2  = 78.07 g/mol

NH4NO2  = 64.06 g/mol

N2O3  = 76.01 g/mol

NH4Cl  = 53.49 g/mol

NH2OH = 33.03 g/mol

In such a way, the compound with the highest percentage of nitrogen by mass is NH4NO2.
