Question

calculate the mass of Nitrogen in 1000 kg of Urea CO (NH2)2

Answer 1

Heya user ,
Here is your answer !!

Molar mass of urea
= 12 + 16 + 2 ( 14 + 2 )
= 28 + 2 × 16
= 28 + 32
= 60 .

Molar mass of nitrogen = 14 .

Amount of nitrogen present by mass in 60 g of urea = 28 g .

So , mass of Nitrogen in 1000 kg of Urea CO(NH2)2 is :--

= ( 28 / 60 ) × 1000 kg
= 466.67 kg ....... [ Ans ]

Hope it helps you !!

Answer 2

Explanation:

(Co(NH2)2)

molar mass = 60gm

60gm urea have 28gm nitrogen so 1000 kg urea will have

28×1000/60 = 467kg nitrogen

hope it helps
