The concentration of tritium in the wine is 0.34 times that found in the freshly bottled wines. If the half life of the tritium is 12.3 years, estimate the time elapsed since the wine was bottled.

Help please. Thank you :)

Use the equations you were given:

\frac{N}{N_o} = \(\frac12\)^{t/h}

You were given that 0.34 N_o = N
h = 12.3 years

You get:


\frac{0.34N_o}{N_o} = \(\frac12\)^{t/12.3}

Solve for t. :)
