Question
A radioactive material has half-life of 10 days. what fraction of the material would remain after 30 days?
Options
A.0.5
B.0.25
C.0.125
D.0.33
Solution
30 days = 3 halflife
Fraction of material remained
=
= 0.125
Fraction of material remained
=
= 0.125Create a free account to view solution
