A liquid sample that weighs 2.585 g is a mixture of butane (C4H10) and hexane (C6H14). When the sample is combusted in an excess of oxygen, 3.929 g of water are formed.
a. How much butane and hexane (answer in g) were in the original sample?
b. How much CO2 (answer in g) was produced in the combustion of the sample?
