Question

You analyze the ratio of radioisotope carbon 14, or ¹⁴C, in these fossil bones. ¹⁴C has a half-life of about 5,000 years. You calculate that these fossil bones have about 12.5% of their original amount of ¹⁴C left. Based on this, you calculate that the fossil bones _______ and thus the age of this human habitation site ________ are around.

Answer 1

15003.19

Step-by-step explanation:

The fossil bones age can calculated by using the formula

t = (In ( 12.5 /100) / (-λ)) × half life

where λ = 0.693

t = ((In (12.5 /100) / (-0.693) ) × 5000 = 15003.19 years

the age of the fossil bones is 15003.19

thus the age of the human habitation site 15003.19
