The half life of Po-218 is three minutes. How much of a 200 atom sample will remain after 15 minutes
MakcuM [25]
<h3>Answer:</h3>

6.25 atoms

<h3>Explanation:</h3>

<u>We are given</u>;

  • The half life of Po-218 is 3 minutes
  • Initial sample is 200 atom
  • Time of decay is 15 minutes

We are required to calculate the remaining mass after decay;

Half life refers to the time taken for original amount of a radioactive sample to decay to a half.

To calculate the remaining mass we use the formula;

N = N₀ × 0.5^n where n is the number of half lives, N is the new amount and N₀ is the original amount.

n = 15 min ÷ 3 min

  = 5

Therefore;

New amount = 200 atom × 0.5^5

                      = 6.25 atoms

Therefore; the amount of the sample that will remain after 15 minutes is 6.25 atoms.
