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

Show us your attempts. What equations are you using? What are you getting stuck on?We can't just solve it for you, but we can help figure out where you're going wrong.
 
..

thats the problem, I am not to sure which equation i shoudl be using
 
Activity and half life in the same equation, do you know an equation that satisfy this?
