Hi guys 
.
A quantity of oxygen gas had 16.32g of the radioactive isotope oxygen-19 in it. When measured exactly 10 minutes later, the amount of oxygen-19 was 0.964g. What is the half-life, in seconds, of oxygen-19?
Y= a (1+i)[sup:1zyj7sgf]t[/sup:1zyj7sgf]
Okay, so, my question is how do i find the value of i? Would it be:
(16.32-0.96)/10
= 1.5
= 0.15%
