(C= 12, O = 16, N = 14 and H = 1)

Question

Urea is a very important nitrogenous fertilizer. Its formula is CON₂H₄. Calculate the percentage of carbon in urea. (C= 12, O = 16, N = 14 and H = 1)

KnowledgeBoat · Accepted Answer

Relative molecular mass of CON₂H₄ = 12 + 16 + 2 x 14 + 4 x 1 = 12 + 16 + 28 + 4 = 60 amu Wt. of C in CON₂H₄ = 12 g % of C = = x 100 = 20% ∴ Carbon in Urea is 20%
