If the half life of substance is 5 years, then the total amount of the substance left after 15 years, when initial amount is 64 gms is

Options

  1. A6 gm
  2. B8 gm
  3. C10 gm
  4. D12 gm

Correct answer

B. 8 gm

Step-by-step solution

Initial amount =64 gms Half life period =5 : years Amount of substance left after 5 years = 64 2 =32 gms Amount of substance left after 10 years = 32 2 =16 gms Amount of substance left after 15 years = 16 2 =8 gms
