A radioactive medical sample contains 2.88 micrograms of an isotope with a half-life of 23 days. The sample is left in the analysis lab for 92 days. What mass of the isotope is left?

Interpretation Introduction

Interpretation:

The mass of the isotope left after 92 day for the given mass and half-life of isotope, is to be determined.

Concept Introduction:

The time needed for a quantity to minimize it to half its initial amount is known as half-life. It can be represented as t1/2.

The elements which consist of the same atomic number and different mass number are known as isotopes.

Explanation of Solution

Given information:

A radioactive medical sample contains 2.88 micrograms of an isotope with a half-life of 23 days. The sample is left in the analysis lab for 92 days.

Four half-lives will be equivalent to 92 days because the half-life is 23 days
