The halflife of polonium 210Po is 143 days If you have 24 gr

The half-life of polonium (210Po) is 143 days. If you have 24 grams now, how much will you have at the end of two years? (3 decimal places)

Solution

Solution:

  P = 24 * (1/2)^{(t / 143)}

t = 2*365 = 730

P = 24 * (1/2)^(730/143)

P = 0.69745038741

P =0.726 grams
