Question: When a sample from a meteorite is analyzed, it is determined that 93.8% of the original mass of a certain radioactive isotope is still present.

When a sample from a meteorite is analyzed, it is determined that 93.8% of the original mass of a certain radioactive isotope is still present. Based on this finding, the age of the meteorite is calculated to be 4.51 × 109 yr. What is the half-life (in yr) of the isotope used to date the meteorite?
