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 :)

time

= -(half life)*ln(fraction remaining)/ln(2)

= -(12.3)*(0.34)/ln(2)

= 19.1 years.

Cesium-137 has a half life of 30.0 years. If initially there are 8.0 kg of cesium-137 present in a sample, how many kg will remain after 60.0 years?
