The original amount of the radioactive isotope will be 8 grams.
The amount of time required for half of a radioisotope's nuclide to decay, or change into a different species, is known as its half-life. The conversions release either beta or alpha particles, and the response can be monitored by counting the particles released.
Given that an unknown amount of a radioactive isotope with a half-life of 2.0 h was observed for 6.0 h. if the amount of the isotope remaining after 6.0 h was 24 g.
The original amount will be calculated as below:-
( 2 / 6 ) = ( Original amount / 24 )
Original amount = 4 x 2
Original amount = 8 grams
Therefore, the original amount of the radioactive isotope will be 8 grams.
