Most fertilizers consist of nitrogen-containing compounds such as NH3, CO(NH2)2, NH4NO3, and (NH4)2SO4. Plants use the nitrogen content in these compounds for protein synthesis. (Express your answer using four significant figures.)

Calculate the mass percent composition of nitrogen in NH3.

Calculate the mass percent composition of nitrogen in CO(NH2)2.

Calculate the mass percent composition of nitrogen in NH4NO3.

Calculate the mass percent composition of nitrogen in (NH4)2SO4.

Which fertilizer has the highest nitrogen content?

Step 1

Formula to calculate % composition:

Mass % of element = mass of the element on the given formula / molecular mass of the compound X 100

Step 2

Mass percent composition of nitrogen in NH3 :

Formula :

Mass % = mass of the element on the given formula / molecular mass of the compound X 100

Molar mass of Ammonia = 17.031

Mass % = 14.007/17.031 x 100 = 82.2 %

Mass percent composition of nitrogen in CO(NH2)2 :

Formula :

Mass % = mass of the element on the given formula / molecular mass of the compound X 100

Molar mass of CO(NH2)2 = 60.06

= [(14.01 X 2)/60.06] x 100% = (28.02/60.06)x100% = 46.65%

Mass percent composition of nitrogen in NH4NO3:

Formula :

Mass % = mass of the element on the giv...
