I'm having second thoughts on the answers I came up with...
Einsteinium-235 decays at a rate of 3.406% per day.
a. find the annual decay rate in exact form:
b. Compute an approximation of your solution in part a accurate to two decimal places:
(This is where I was thrown off, as my equation truncated to two decimal places comes out to be 0.00, and I'm sure that's not the intention.)
3.21 x 10^-4
c. Find the half-life of Einsteinium-235 in exact form:
t x log(96.594)=log(50)
d. Compute an approximation of your solution in part c accurate to two decimal places
(But I know that's obviously wrong. (Headbang))
Any help appreciated.
Half-life can easily be gotten from the formula
You know k, enter it in and solve for T.
What about my decay rate?
