🤓 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(NH2)2 and to do that we’re going to use the mass percent formula shown below:
For the percent by mass N, we’re going to rewrite the equation as:
Most fertilizers consist of nitrogen-containing compounds such as NH3, CO(NH2 )2, NH4 NO3, and (NH4 )2 SO4. Plants use the nitrogen content in these compounds for protein synthesis.
Calculate the mass percent composition of nitrogen in CO(NH2 )2.
