Answer:
If the half life is a year, that means after 1 year there’s half of it left. I don’t suppose you need me to calculate 500/2 for you.
29=512 , so after 9 years there will be 500/512 g left, a bit less than 1 g.
Step-by-step explanation:
After Tn years, the mass is f(Tn)=500⋅0.5Tn grams
500⋅(12)Tn=12Tn=500Tn=log2(500)≈8.97mass <1 gram in ninth year.
