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.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
