Nuclear decay occurs according to first-order kinetics. Argon-37 decays with a rate constant of 0.0198 days\(^{-1}\). After 98.3 days, a sample has a mass of 2.14 g. What was the original mass of the sample?

Answer :

The original mass of the sample was 14.79 grams.

We know that rate of reaction of first order reactions is given by: [tex]kt = 2.303* log(R'/R)[/tex]

where k = rate of reaction = 0.0198

t = time = 98.3 days

R = final mass = 2.14 grams

Putting these values in above equation we get R' = 14.79 grams.

i.e. The original mass of the sample was 14.79 grams.
