Solution: Drinking alcohol is also called ethyl alcohol or ethanol. Most of the ethanol produced in the USA comes from corn, an obviously natural source. It can also be made in the laboratory from natural gas (CH4) as a starting material. If you wanted to use ethanol from one of these sources, and price were not a consideration, decide which one you would choose. Which of the following laws listed below is most useful to you in making your decision?   a. The Law of Conservation of Mass b. The Law of Definite Proportions c. Dalton’s Atomic Theory d. The Law of Multiple Proportions e. Avogadro’s Hypothesis
