How much of 8-gram sample of Hydrogen-3 would still be present after 12.3 years if the half life of a H-3 is 12.3 years?
If 12.3 years is the half-life of Tritium (H-3), then @ 12.3 years only half of the tritium should remain or 4 grams.

Which element has Highest half life period?
i guess it's Tellurium 128, with a half life of 2.2e24; you may consider it a stable isotope as well.
After 36.9 years a sample of hydrogen contains one-eighth the amount it contained originally what is the half-life of the isotope?
The half-life of the isotope in question is 12.3 years. This can be calculated by dividing the time it took for the sample to decrease to one-eighth its original amount (36.9 years) by 3, which represents the number of half-lives it took to reach that point.
How much hydrogen-3 will remain after 60 years if the original sample have a mass 80.0 g and a the half-life of hydrogen-3 is 12 years?
Fraction remaining = 0.5^n where n = # of half lives that have elapsed60 yrs x 1 half life/12 yrs = 5 half lives have elapsed Fraction remaining = 0.5^5 = 0.03125 mass remaining = 0.03125 x 80.0 g = 2.5 g remaining
Which element has the lowest half-life?
Bismuth has recently been found to have a no stable isotope and has a half-life of 4.6 x 10^19 years. Also, the simple hydrogen atom (a single proton), is theorized to decay at a rate of 6.6 x 10^33 years. So far all tests to observe a proton decay have failed.
