Question

If the initial sample is 1.25 g, what mass of the original iridium‑192 remains after 65 days?

mass remaining:
0.675 g (this is correct, I just need answers to the last two questions)
Estimate the half‑life of the radioisotope.
half-life: days
How many days would it take for one‑third of the sample to decay?
time:

Iridium-192 is one radioisotope used in brachytherapy, in which a radioactive source is placed inside a patient's body to treat
cancer. Brachytherapy allows the use of a higher than normal dose to be placed near the tumor while lowering the risk of damage
to healthy tissue. Iridium-192 is often used in the head or breast.
Use the radioactive decay curve of iridium-192 to answer the three questions.
