The given question is incomplete. The complete question is :
This is the chemical formula for carvone (the chemical that gives spearmint its flavor) 
: 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 .
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 , 
mole of oxygen is there in carvone.
Thus 2.73 moles of oxygen are there in the sample.
Oxygen has to be involved when methanol is ignited
Two parts are stage and coarse focus
Answer:
Homogenous mixture
Explanation:
Homogenous mixtures like ice cream appear to be uniform, and you cannot see their individual components.
The numbers may be off by a few, if you worked it out, since my periodic table is for AP chemistry. Hope this helps!!!
