First, we need to get the atomic weights of each element in (NH4)2SO4 using the periodic table and then calculate its molar mass.
molar mass N = 14.01 g/mol
molar mass H = 1.01 g/mol
molar mass S = 32.06 g/mol
molar mass O = 16.00 g/mol
molar mass (NH4)2SO4 = (14.01 g/mol x 2) + (1.01 g/mol x 8) + 32.06 g/mol + (16.00 g/mol x 4)
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 (NH4 )2 SO4.
