A 3650​-year-old wooden chest is found by archaeologists. What percentage of the original Superscript 14 Baseline Upper C would
AfilCa [17]

Answer:

64.5%

Step-by-step explanation:

Initial amount N° = ?

Remaining amount after decay = N = ?

k = decay constant =  0.00012 yr^{-1}

t = time = 3650​ year

fraction remaining will be N/N°

From the decay equation, N = N°e^{-kt}

N/N° = e^{-kt}

N/N° = e^{-0.00012 x 3650 }

N/N° = e^{-0.438}

N/N° = 0.645 = 64.5%
