Question

calculate the mass of nitrogen in 1000 kg of urea , CO(NH2)2

Answer 1

Hi.

Here is your answer-----

Mass of the urea given = 1000 kg.
                                     = 1000 x 1000 g.
                                     = 1000000 g.

Chemical formula of the urea{carbamide} is NH2CONH2

Molecular Mass of the Urea = 60 grams.

The mass of Nitrogen present in 60 grams of the Urea = 28 grams.

Since, 60 grams of the urea contains 28 grams of the Nitrogen.

Thus, 1 grams--------------------------------------------28/60 grams of the N2

Therefore,

1000000 grams -------------------------------(28/60) x 1000000 grams of N2
                                                               = 466666.666667 grams of N2

Here is your answer.

Have a nice day.

Answer 2

Explanation:

(Co(NH2)2)

molar mass = 60gm

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

28×1000/60 = 467kg nitrogen
