The half-life of a sample of 1011 atoms that decay by alpha particle emission is 10 min?How many alpha particles are emitted in the time interval from 10 min to 100 min?
please help me and show work as fast as possible
Homework Answers
A 10 min the fraction that remains will be 1/2 of the
original
And at 100 mins the fraction that remains will be 1/(2 ^10) of the
original
so the amount lost in the time interval is 10 ^11 * (1/2 - 1/2 ^
10) = 4.99 * 10 ^ 10
