🤓 Based on our data, we think this question is relevant for Professor Tomasik's class at CMU.

We are asked to calculate for the **percent by mass (% mass ) of N**** in Co(NH _{2})**

$\overline{){\mathbf{mass}}{\mathbf{}}{\mathbf{percent}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{mass}\mathbf{}\mathbf{element}}{\mathbf{total}\mathbf{}\mathbf{mass}\mathbf{}\mathbf{of}\mathbf{}\mathbf{compound}}{\mathbf{\times}}{\mathbf{100}}}$

For the **percent by mass N**, we’re going to rewrite the equation as:

Most fertilizers consist of nitrogen-containing compounds such as NH_{3}, CO(NH_{2} )_{2}, NH_{4} NO_{3}, and (NH_{4} )_{2} SO_{4}. Plants use
the nitrogen content in these compounds for protein synthesis.

Calculate the mass percent composition of nitrogen in CO(NH_{2} )_{2}.
