Abottle of vintage red wine has lost its label. the concentration of a radioactive isotope of hydrogen (hydrogen-3 or tritium) in the wine is 0.34 times that found in freshly bottled wines. if the half-life of tritium is 12.3 years, calculate the time elapsed since the wine was bottled. this is a first order decay.
