Question

This is the chemical formula for carvone (the chemical that gives spearmint its flavor): An organic chemist has determined by measurements that there are moles of carbon in a sample of carvone. How many moles of oxygen are in the sample

Answer 1

The given question is incomplete. The complete question is :

This is the chemical formula for carvone (the chemical that gives spearmint its flavor) $C_{10}H_{14}O$: An organic chemist has determined by measurements that there are 27.3 moles of carbon in a sample of carvone. How many moles of oxygen are in the sample

Answer: 2.73 moles of oxygen are there in the sample.

Explanation:

The chemical formula of carvone is $C_{10}H_{14}O$.

This means:

When 10 moles of carbon are there in carvone , 1 mole of oxygen is there in carvone

Thus for 27.3 moles of carbon in carvone , $\frac{1}{10}\times 27.3=2.73$ mole of oxygen is there in carvone.

Thus 2.73 moles of oxygen are there in the sample.
