Converting Decimals to Fractions Note that each of the decimals you have encountered thus far in this activity end after a few digits. Decimals such as these are referred to as terminating decimals. When a terminating decimal is written as a fraction or mixed number, the denominator corresponds to the place value of the rightmost digit in the decimal. This leads to the…

While you are working in a hospital laboratory, a patient complaining of severe stomach cramps and labored respiration dies within minutes of being admitted. Relatives of the patient tell you that he may have ingested rat poison. Therefore, you have his stomach pumped to verify this and to determine the cause of death. One of the more logical things to do would be to attempt to isolate the agent that caused death and perform chemical analyses on it. Assume that this was done, and the analyses showed that the isolated chemical compound contained, by weight, 60.0% potassium, 18.5% carbon, and 21.5% nitrogen. What is the chemical formula for this compound?
