In summary, the question involves calculating the volume of a stock solution of 32PO43- with a known activity and half life, in order to provide a desired activity at a specific time. The specific equation to use may depend on the context, but incorporating the concepts of activity and half life should lead to a solution.

Carbon dating!..urgent help needed

Homework Statement



-- The half life of the isotope 32P is 14.28 days. A stock solution of 32PO43 contained 7659 Bq of activity in 25 cm3 at 09.00 hours on the 7th June. 250Bq of 32P is required for an experiment starting at 15.00 hours on the 19th June. What volume of the stock solution of 32PO43- would be required to give the desired activity at 15.00 hours on the 19th June

Ive had a few attempts at this and don't seem to have much idea of how to solve this question, could anyone help solve it urgently?

Please help
Thanks

Activity and half life in the same equation, do you know an equation that satisfy this?
 

FAQ: Calculating 32P Half-Life for Urgent Experiment: Stock Solution Needed

What is carbon dating and how does it work?

Carbon dating is a method used by scientists to determine the age of organic materials. It relies on the fact that all living organisms contain carbon, including a small amount of radioactive carbon-14. This carbon-14 decays at a known rate, allowing scientists to measure the amount of carbon-14 remaining in a sample and calculate its age.

What types of materials can be dated using carbon dating?

Carbon dating can be used to date organic materials such as wood, bone, and charcoal. It is not effective for dating inorganic materials such as rocks or minerals.

How accurate is carbon dating?

Carbon dating is considered to be accurate within a range of about 50,000 years. However, the accuracy can be affected by a number of factors, such as contamination of the sample or changes in the amount of carbon-14 in the atmosphere over time.

What are the limitations of carbon dating?

Carbon dating is not able to provide precise dates for materials that are older than 50,000 years. It also cannot be used to date materials that have not been part of the carbon cycle, such as shells or fossils. Additionally, it may not be accurate for samples that have been exposed to extreme temperatures or environmental conditions.

How is carbon dating used in other fields of science?

Carbon dating is not only used in archaeology and anthropology, but also in other fields such as geology, paleontology, and environmental science. It can be used to determine the age of fossils and geological formations, track the movement of pollutants, and study past climate changes.
