Given that sodium-24 has a radioactive half-life of approximately 15 hours, how much of a 5 kg sample of sodium-24 would be left after 1.5 hours? Note that the equation A(t) = Aga' describes the amount of sodium-24 remaining after I hours (as usual. Ao is the amount at time = 0). Round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to three decimal places.
