Answer to Question #74695 in Organic Chemistry for Aarti

Question

Normal water contain isotope of hydrogen H3 tritium. It has a half life of 12.è years.Determine the age of a bottle of wine whose H3 radiation is about 1/10 that present in new wine.

Answer 1

Half-time T = 12.3 years.
The age of a bottle t:
T = - tln2/ln∆N
-tln2 = Tln∆N
t = Tln∆N/-ln2 = 12.3•ln(0,1)/-ln2 = 12.3•(-2.3) / -0.693 =40.82 years
