Question: The curie Ci is a commonly used unit for measuring
The curie (Ci) is a commonly used unit for measuring nuclear radioactivity: 1 curie of radiation is equal to 3.7 X 1010 decay events per second. A 1.7-mL sample of w’ater containing tritium was injected into a 150-lb person. The total activity of radiation injected was 86.5 mCi. After some tune to allow the tritium activity to equally distribute throughout the body, a sample of blood plasma containing 2.0 mL water at an activity of 3.6 µCi was removed. From these data, calculate the mass percent of water in this 150-lb person.

What is the difference between a saturated hydrocarbon and an unsaturated hydrocarbon? Distinguish between normal and branched hydrocarbons. Draw the structure for 4-ethyl-2,3-diisopropylpentane. This name is incorrect. Give the correct systematic name. There is only one compound that is named 1, 2-dichloro-ethane, but there are two distinct compounds that can be named 1,2-dichloroethene. Why? Draw all the structural isomers of C5H10. Ignore any cyclic isomers. Which of the structural isomers exhibit cis-trans isomerism?
