Number of atoms of N,C & O.​

Answer 1

Here is your answer mate ✔️

Urea→CO(NH

2

)

Given weight = 5.6g

∴ Moles of urea =

60

5.6

=0.0933 moles

No. of H atoms =4×0.0933×Na=2.25×10

23

atoms

No. of N atoms =2×0.0933×Na=1.123×10

23

atoms

No. of C atoms =No.ofOatoms=0.0933×Na=5.6×10

22

atoms
