A 10.00 g sample of wood from an archaeological site produced 3072$\beta$- particles in a 10-hour measurement owing to the presence of carbon-14, while a 10.00 g sample of new wood produced 9216 $\beta$- particles in the same period of time.The half-life of carbon-14 is 5730 years.How old is the wood from the archaeological site?

Question

Quizplus · Accepted Answer

The correct answer is A because the age of the wood can be calculated using the formula:Age = (ln(Sample activity / Modern activity) / ln(0.5)) * Half-lifePlugging in the given values, we get:Age = (ln(3072 / 9216) / ln(0.5)) * 5730 years= 9080 years
