Question

What is the mass of nitrogen in 1000 kg of urea [CO(NH₂)₂]?
(H = 1; C = 12; N = 14; O = 16)

Open in App

Solution

Mass of nitrogen in urea molecule = (2 $\times$ 14) g = 28 g
Molecular mass of urea = [12 + 16 + 2 (14 + 1 + 1)] g = 60 g
60 g of urea contains 28 g of nitrogen.
Mass of nitrogen in 1000 kg of urea = $\frac{28}{60} \times 1000 kg = 466.7 kg$
