Question

# The percentage of nitrogen in urea is:

- 46
- 23
- 48
- 52

Hint:

### Mass percentage of N= Total mass of N atoms in the compound/ Molecular mass of the compound *100

## The correct answer is: 46

### Mass percentage of N= Total mass of Nitrogen atoms in the compound/Molecular Mass of the compound *100

Molecular mass of urea=60

=28/60*100

=46.6%
