Urea is a very important nitrogenous fertiliser. Its formula is `CON_(2)H_(4)`. Calculate the percentage of nitrogen in urea. (C = 12, O = 16, N = 14 and H = 1)

Text Solution

Verified by Experts

`CO(NH_(2))_(2)`
Molecular mass = `12+16+2(14+2)=60`
Percentage of nitrogen = `("Mass of nitrogen in the compound")/("Molecular mass")xx100`
= `28/60xx100=46.67%`
