Can you please explain how we are using the half life equation in this question? to get mass in grams after 13 days. The question is as follows:
Gallium-67 (t 1/2 = 78.25 hours) is used to diagnose certain tumors. If you ingest 0.055 mg of 67 GA what mass will remain in 13 days.
I started out using the integrated rate law to get K must have K to do half-life equation correct? and then to the 1/2 life equation. Do hours always have to be converted to seconds?
We have the half-life equation as,
t_1/2 = 0.693/lambda where lambda is the disintegration constant
==> lambda = ...
The solution provides and easy to follow explanation of the concepts and gives all mathematical steps wherever necessary.
