Phosphorus-32 is a commonly used radioactive nuclide in biochemical research, particularly in studies of nucleic acids. The half-life of phosphorus-32 is 14.3 days. What mass of phosphorus-32 is left from an original sample of 175 mg of Na332PCO4 after 35.0 days? Assume that the atomic mass of 32P is 32.0.
Answer to relevant QuestionsA chemist wishing to do an experiment requiring 47Ca2+ (half-life = 4.5 days) needs 5.0 µg of the nuclide. What mass of 47CaCO3 must be ordered if it takes 48 h for delivery from the supplier? Assume that the atomic mass of ...During World War II, tritium (3H) was a component of fluorescent watch dials and hands. Assume you have such a watch that was made in January 1944. If 17% or more of the original tritium was needed to read the dial in dark ...Calculate the binding energy per nucleon for 21H and 31H. The atomic masses are 21H, 2.01410 amu, and 31H, 3.01605 amu. Define fission and fusion. Fusion processes are more likely to occur for lighter elements, whereas fission processes are more likely to occur for heavier elements. Explain. Consider the following information: i. The layer of dead skin on our bodies is sufficient to protect us from most α-particle radiation. ii. Plutonium is an α-particle producer. iii. The chemistry of Pu4+ is similar to that ...
