An artifact originally had 16 grams of carbon-14 present. The decay model A = 16 e^-0.00012 describes the amount of carbon-14 present after 1 years. Use the model to determine how many grams of carbon-14 will be present in 9535 years. The amount of carbon-14 present in 9535 years will be approximately grams. (Round to the nearest whole number.)

Solution

A = 16e^(-0.000121t)

after t = 9535 yrs

A = 16e^(-0.000121*9535)

=16*0.2149

= 3.439

= 3 gms
