How many mol of nitrogen is in 0.30 mol of caffeine

In the given amount of caffeine, 1.2 moles of nitrogen is there.

Explanation:

The chemical formula for caffeine molecule is

This is formed by the combination of carbon, hydrogen, nitrogen and oxygen atoms.

In 1 mole of caffeine molecule, 8 moles of carbon atom, 10 moles of hydrogen atom, 4 moles of nitrogen atom and 2 moles of oxygen atoms are present.

We are given:

Moles of caffeine = 0.30 moles

So, in 0.3 moles of caffeine, (0.3 × 4) = 1.2 moles of nitrogen atom will be there.

Hence, in the given amount of caffeine, 1.2 moles of nitrogen is there.
