Question
If a radiometric element has a half-life of 425 years, how old would a rock be that only had $3.125 \%$ of the parent isotope remaining?a. 2125 yearsb. 1700 yearsc. 2550 yearsd. 3400 years
Step 1
First, we need to determine how many half-lives have passed for the rock to have only 3.125% of the parent isotope remaining. Show more…
