Determining the amount of radioisotope remaining at a given time?

∙ 13y ago
If you know the 'half-life' of that isotope, call that period of time ' L ',
call the beginning amount ' B ', and call the amount of time that has
passed since the beginning ' T '.
The amount that remains at time ' T ' is
(B) divided by (2T/L).

What is the primary technique for determining the absolute age of a rock?
well its do to the sediment in a rock by it layering
What is half-life of a radioistope is the amount of time it takes for?
The time depends on the isotope. The half life of uranium-238 is about 4.47 billion years and that of uranium-235 is 704 million years. The half life is the amount of time during which any given atom of the isotope has a 50% chance of undergoing decay. Seen another way, the half life is the time it takes for half the atoms of an isotope in a mass of that isotope to undergo decay.
What is the amount of matter given in volume?
The amount of matter is mass. Volume is the amount of space that matter takes up. The amount of matter in a given volume is density.
How much time is needed for radioisotope to decay into its stable daughter product?
There is no one answer for an individual atom, but for a given radioisotope we usually quantify the rate of decay via the half-life, i.e. the average time it takes for half of the atoms of an isotope to decay. Realizing that some isotopes will decay to another radioisotope before eventually decaying to a stable product, this can get even more complicated. In mathematical terms the equation for concentration of the radioisotope approaches zero asymptotically. The math says that you will never get zero concentration - but of course atoms are discrete entities so that once the concentration predicted by the math drops below one atom, you have reached zero in the real world.
