Question

Calculate the mass of nitrogen in 6kg urea

Answer 1

Answer:

First, you need to take into consideration the formula of Urea to figure out it's mass.

WHich is NH2-CO-NH2.

Thus it's mass is 60gm (molar)

There fore moles of molecules in 6gm Urea = Given Mass/molar mass

=6/60= 0.1 moles.

But if we need the moles of atoms, IN each molecule we have 8 atoms, thus number of moles of atoms = 8*0.1 = 0.8 moles.

Please inform is wrong, approve if correct.
