Cobalt-60 has a half life of 5.25 years. if you started with a 40 gram sample of pure cobalt-60, how many grams of cobalt-60 would remain after 10.5 years?

Answers

ansver
Answer from: sross8799

10 grams

Explanation:

A = A₀ (½)^(t / T)

A = 40 (½)^(10.5 / 5.25)

A = 40 (½)^2

A = 40 · ¼

A = 10
