The age of wine can be determined by measuring the trace amount of radioactive tritium, 3H, present in a sample. Tritium is formed
from hydrogen in water vapor in the upper atmosphere by cosmic bombardment, so all naturally ocurring water contains a small
amount of this isotope. Once the water is in a bottle of wine, however, the formation of additional tritium from the water is negligible,
so the tritium initially present gradually diminishes by a first-order radioactive decay with a half-life of 12.5 years. If a bottle of wine is
found to have a tritium concentration that is 0.191 that of freshly bottled wine (i.e. [³H]; = 0.191[°H]o), what is the age of the wine?
