The half-life of a radioactive isotope is 2.5 min. If there are initially 48 Times 10^32 atoms of this isotope, (a) the number of atoms of this isotope remaining after 15 min is: 12 Times 10^32 7.5 Times 10^31 3 Times 10^32 6 Times 10^4 3 Times 10^2 (b) what is the decay constant?

The number of radioactive isotopes in a sample, N(t) as a
function of time is given by an exponential law
where N(0) is the initial number of radioactive
isotopes at time t=0, and k is a constant. Find the expression for
t1/f, the time it takes for N(t) to go from its initial
value to N(o)/f. What is the value for X in the following
expression?

I only need help with part c). Thanks!
As a radioactive specimen decays, its activity decreases exponentially as the number of radioactive atoms diminishes. Some radioactive species have mean lives in the millions (or even billions) of years, so their exponential decay is not readily apparent. On the other hand, many species have mean lives of minutes or hours, for their exponential decay is easily observed. According to the exponential decay law, the number of radioactive atoms that remain after...

3 pts It is handy to have an equation to quickly determine the number of atoms left in a radioactive sample as a function of time. For this we can divide the initial amount by two for every half-life of time, the following equation does exactly that: N No (24/01/2) N, 2 1/2 where N is the initial number of atoms at t=0, t is time passed and is the half-life. Use the above equation to help you answer the...
