Question

Please don't provide handwritten solution ....

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. If the initial sample is 3.50g, what mass of the original iridium- 192 remains after 105 days?
