1. A friend claims that a metric ton is more than twice the mass of an English ton because akilogram is more than twice the mass of a pound. Make a quantitative argument in support of oragainst your friend's claim. (1 page)2. Upgraded U.S. fuel economy standards formalized in 2012 call for a 54.5 mile-per-galloonaverage for new cars and light trucks in 2025. A politician opposing this increase claims it willsave "only a drop in the bucket" compared with the 2014 fleet average of about 23 mpg.Formulate a counterargument showing that the increase - once the entire fleet reaches 54.5 mpg- consumption rate from its 2014 value of about 375 million gallons per day. State any additionalassumptions you make.

Commercial ibuprofen tablets contain 200 mg of ibuprofen each. The commercial tablets have the active ingredient (ibuprofen) in addition to several other additives (e.g. starch, sucrose, etc) to assist in digestion. There are 6 tablets that are used in the experiment. The maximum amount of available ibuprofen is (6 x 200 mg) = 1200 mg. Six pills Pure Ibup (after m.p. recrys.) Crude ibup.
