Can anyone solve this problem for me please. I need answers and just a hint how to solve it
Initially the amount of A(0) of a decaying substance is 12g. Find the half life t1/2 of the substance and how long it will take to completely decay if there is 9g left after an hour and the decay rate A/(t) is
a)constant
t1/2 = ________t disappear = _____________
b)proportional to time t
t1/2 = ________t disappear = _____________
c)proportional to the amount A(t) present at time t
t1/2 = ________t disappear = _____________
