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

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

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.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
