If a sample of radioactive isotopes takes 60 minutes to decay from 200 grams to 50 grams, what is the half-life of the isotope

I HOPE IT WILL BE YOUR ANSWER:

Explanation:

As given

60 min = 50 gm        (1)

then we know half-life mean half amount decay time

so we can write as the half of 200 is 100 gm hence

T 1/2 = 100               (2)

solving these two equation by cross multiplication we will get

T 1/2 = 120 min
