Answer to Question #47761 in Inorganic Chemistry for Shabreka Edwards

Question #47761
What mass of melamine, C3N3(NH2)3, will be obtained from 137.0kg of urea, CO(NH2)2, if the yield of the overall reaction is 77.0% ? Express your answer to three significant figures and include the appropriate units.
Expert's answer
6 (NH2)2CO → C3H6N6 + 6 NH3 + 3 CO2
M(urea) = 60 kmoles/kg
From 6 x 60 kg of urea it is produced 126 kg of melamine;
From 137.0 kg – X kg
X = 47.95 kg (of melamine)
If the yield is 77% so the mass of melamine will be 47.95 x 0.77 = 36.9215kg
Answer: ~36.922 kg
