Question
![The problem presented is related to the concept of half-life in radioisotopes.
**Question:**
"The half-life of the radioisotope \[ _{63}^{158}\text{Eu} \] is 1.0 hour. How many hours will the decay of a 160-g sample of the isotope to 1.25 g require?"
**Options:**
- 3.0
- 4.0
- 5.0
- 6.0
- 7.0
This is a multiple-choice question where we need to calculate the time it takes for a given sample of a radioisotope to decay from its initial mass to a specified smaller mass, based on the half-life of the substance. The focus is on applying knowledge of exponential decay and half-life to solve the problem.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3b759eb6-92d1-410c-9c5f-e87a5e392771%2F7e90f693-542a-4115-a4a9-5ab88f884bf4%2F9fh8lnf_processed.jpeg&w=3840&q=75)
