16 grams of radioactive material decays into 8 grams in 10
years. How long will it take to decay to 1 gram?
Answer Posted / valarmathy
16 gm reduced to 8gm in 10yrs
so 8 gm get decayed
for decaying 1 gm it takes 10/8 yrs
for decaying 8 gm it takes 10/8*8
remaining 8 gm
need to decay 7 to get 1 gm remaining
for decaying 7 it takes
10/8*8*7
=10*7
=70 years
