49 19K isotope of potassium has a half-life of 1.4×10^9 yr and decays to form stable argon, 40 18Ar. A sample of rock has been taken which contains both potassium and argon in the ratio 1:7, i.e., (Number of potassium-14a→ms)/(Number of argon-40a→ms)=12 Assuming that when the rock was formed no argon −40 was present in the sample and none has escaped subsequently, determine the age of the rock.
