Problema Solution
Carbon-14 has a half-life of 5730 years. After 17190 years 1/8 of the carbon is left. If 5 grams are left after 17190 years how much carbon was in the original sample.
Answer provided by our tutors
Let 'x' represent the amount of carbon in the original sample.
(1/8)x = 5 multiply both sides by 8
x = 5*8
x = 40 g
There were 40 grams of carbon in the original sample.
