Complete the table for the radioactive Isotope Find the expo

Complete the table for the radioactive Isotope. Find the exponential model that fits the points shown In the table.

Solution

Half lig=fe = 1599 yrs ; intial amt = 11gm

decay constant = 0.693/1599 =0.00043 /yr

N= Noe^-kt

N =11e^-0.00043t

After t = 1000 yr ; N = 11e^(-0.00043*1000) = 11*0.6505 = 7.155

= 7.16 gm
