The half-life of silicon-32 is 710 years. If 10 grams are presents now, how much will be present in 600 years?
;
The half-life equation:
A = Ao(2^(-t/h))
Where:
A = resulting amt after t years
Ao = initial amt
t = time
h = half-life of the substance
:
In your problem, find A when:
Ao = 10 grams
t = 600 years
h = 710 yrs is the half life of silicon-32
:
A = 10(2^(-600/710))
A = 10*.55668; find 2^(-60/71) on a good calculator
A = 5.5668 grams after 600 yrs

That's not so hard, is it?
