The quantity Q of radioactive carbon remaining in a 200-gram wood sample at time t is given by the expression

Question

Q(t)=200e^(−0.000225⋅t).

How much radioactive carbon remains in the sample after 100500 years?

I just plugged in 100500 as t and got 3.02375 grams as an answer. Is this correct?

Answer 1

the 3.02375 is correct, but you lost a factor of 10^-8

So, what you really have is .03 micrograms

Answer 2

thanks
