Textbook Question
Chapter 2, Problem 119RQ
The following are models of molecules of two compounds composed of carbon, hydrogen, and oxygen. The one on the left is ethanol, the alcohol that’s added to gasoline with the hope of reducing our dependence on foreign oil supplies. The one on the right is dimethyl ether, a compound that is a gas at room temperature and is used as an aerosol propellant. How many atoms of carbon, hydrogen, and oxygen are in each of these molecules? Find a way to write the formula of one of them using parentheses so that the two compounds can be distinguished one from the other.

Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask.
