Calculate Volume of 24NaI Stock Solution for 1kBq at 8:30am on 4th June

[roley]

Homework Statement

The Half life of the isotope 24Na is 15.00 hours. a stock solution of 24NaI contained 16000Bq of activity in 25cm3 at 5.00 pm on the 2nd of june. An experiment starting at 8:30am on the 4th of june requires 1kBq. What volume of the stock 24NaI solution would be required to give the desired activity at 8:30 am on the 4th of june

Homework Equations

I am not given any equation but the ones that relate to it are the simple half life, decay constant and exponential decay equations

The Attempt at a Solution

I really have no idea where to start in this problem i know this is asking a lot but any indication or support would be greatly appriciated
