How many days does it take for 16 g of palladium-103 to decay to 1.0 g?
The half-life of palladium-103 is 17 days.
The half-life of palladium-103 is 17 days.
1 Answer
It will take 68 days for the palladium to decay.
Explanation:
The formula for the half-life of a first-order process is
#color(blue)(bar(ul(|color(white)(a/a) t_½ = (ln2)/kcolor(white)(a/a)|)))" "#
∴
The integrated formula for a first-order process is
#color(blue)(bar(ul(|color(white)(a/a) ln("A"_0/"A") = ktcolor(white)(a/a)|)))" "#
If we had recognized that the
This is easier, but it works only for an integral number of half-lives.
