Answer:
It will take 50 years to decay from 512 grams to 121.5 grams.
Step-by-step explanation:
The decay formula :
where
N= amount of substance after t time
N₀= initial of substance
t= time.
A substance decays at a rate 25% every 10 years.
So, remaining amount of the substance is = (100%-25%)= 75%
, t= 10
Taking ln both sides
Now , N₀= 512 grams, N= 121.5 grams, t=?
Taking ln both sides
⇒t=50 years
It will take 50 years to decay from 512 grams to 121.5 grams.
