Carbon 14 Has A Half Life Of 5730 Years at Life

Carbon 14 Has A Half Life Of 5730 Years. If a sample contained 70 mg originally, how much is left after 17,190 years. So in 5,717 years, a 1.

If a sample contained 70 mg originally, how much is left after 17,190 years. An archaeologist finds the 14c in a sample of 2.10 g of material to be decaying at 107 bq. If the half life of carbon 14 is 5730 years, then your formula becomes:

NephiCode Why is it so Difficult to Obtain Accurate Dates

The time period in this problem is in years. So, your answer would be the time it. So what in the half life half life means the time it will take for 50% of decay. .5 = 1 * e ^ (r * 5730) this can be simplified to.5 = e ^ (r * 5730) take the natural log of both sides of this equation to get ln(.5) = ln(e ^ (r * 5730)).
