Hi there,
The half-life of a radioactive isotope is
the time it takes for a quantity of the
isotope to be reduced to half its initial Activity.
200 gms - 100 gms 1 half life
100 gms - 50 gms 2 half lives
50 gms - 25 gms 3 half lives
25 gms - 12.5 gms 4 half lives
12.5 gms - 6.25 gms 5 half lives
= 6 gms.
Hope this helps :-)
