### Questions & Answers

**QUESTION:**

The molar mass of caffeine is 194.19 g. Is the molecular formula of caffeine \(\mathrm{C}_4\mathrm{H}_5\mathrm{N}_2\mathrm{O}\) or \(\mathrm{C}_8\mathrm{H}_{10}\mathrm{N}_4\mathrm{O}_2\)?

**ANSWER:**

Step 1 of 2

Here, we are going to determine the molecular formula of caffeine.

We know that,

The molar mass of C = 12.01 g

The molar mass of H=1.008 g

The molar mass of N= 14.00 g

The molar mass of O=16.00 g
