Question

A sample of pure acetic acid contauns 1.40x10^23 carbon atoms. How many moles of acetic acid are in the sample?

Answer 1

.2326 moles of Carbon atoms
Work: 1.4x10^23/6.02x10^23

Answer 2

There are 2 carbons in every one acetic molecule. \[HC _{2}H _{3}O _{2}\] So we use the same equation rnick used and ger .2326 moles then we use the ratio of carbo to acetic to find the answer.\[.2326moleC \times {1molesHC _{2}H _{3}O _{2} \over 2molesC} = .116moles\]
