Freaking Keenan & Wood Chapter 14, Problem 36 could NOT be solved because the Authors Never provided an example for the MATH involved. Thanks for this brain twister. ln(.5)/t=K, then ln(%)/K=t.
A commercial anti-inflammatory drug has an initial content of 1088mg/L.It has a half-life of one and a half hour.In how many hours from now will it take to reduce its content to 34 mg/L.
May I ask your assistance for this problem? Iodine-131 is a radioactive isotope used in medicine. Its half-life or decay rate of 50% is 8 days. If a patient is given 25mg of iodine-131, how much would be left after 32 days or 4 half-lives. Identify C, T, R and the decay factor. Write down the equation you would use and solve.
Thank you so much. You've help me complete my last problem, which I was stuck on for a while.
Awesome explanation, I did not expect the formula to be so complex
rlly needed this for yesterdays test thank you!
Nice explanation! Thank you very much for your help.
Extremely good and wonderfully explained
Appreciated
(ignore my name, its an account i made when i was young) thank you sooo much, i was stressing so hard, this came in clutch.

Solve 1.0g Ra226 (h-l 1620 yrs.) decays in 10 days. What are the amounts of Ra and He?
Hii what if the A0 is given? Do we still cancel it out?
It would still cancel out, because it's the same value on both sides.
yes it would. the value doesn't change
Will we not change days into seconds?
Since the half life is measured in days, you don't have to. If they asked you how many seconds would it take, then you would have to convert.
How did you cancel out the A0 again?
Sorry didn't see this comment. They cancel out, because you're dividing both sides by A0. Anything divided by itself is 1.
Math and Stats Help
Thank you so much, I got an A- is my calculus class.
That's awesome!
