Expert Answer

Step 1

To find out the which contains the most nitrogen, we need to find out the the moles of nitrogen in each case.

a. Given, molecules of C3H6N6= 1.22 × 1024

Atoms of nitrogen can be calculated as:

1molecule of C3HN6 contains
6 atoms of N
6 atoms of N
. 1.22 x 1024 molecules of C3HN6 contain-
x 1.22 x 1024 molecules
1 molecule
= 7.32 x 1024 atoms of N

Step 2

b. Given, moles of C3H6N6= 2.78

Molecules of C3H6N6 can be calculated as:

1 mole 6.022 x 1023 molecules
6.022 x 1023 molecules
:. 2.78 mole
x 2.78 mole
1 mole
= 1.67 x 1024 molecules
Atoms of nitrogen can be calculated as:
1 molecule of C3HN6 contains-
6 atoms of N
6 atoms of N
. 1.67 x 1024 molecules of C3H6N6 contain
1.67 x 1024 molecules
1 molecule
= 10.02 x 1024 atoms of N
