![The age of wine can be determined by measuring the trace amount of radioactive tritium, SH, 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 0.155 that of freshly bottled wine (i.e. [H]; = 0.155 [°H]o), what is the age of the wine?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd3f48f82-e14f-4a9f-a2aa-a0bbe6e3e5b8%2Fb6d91f6a-5a7c-4951-85da-9dd75f414a9e%2Fwmvvtu_processed.png&w=3840&q=75)
