Question 1113943: The half-life of a particular radioactive isotope is 72 hours.
Write an equation to relate the mass of radioactive material remaining to time (in hours).
Starting with 170g, what mass will remain in 3 weeks?
If after one day (24 hours), a different sample of the material was found to have a mass of 14 mg with a half-life of 12h, what was the initial mass of the sample?
solve using log if possible

The half-life of a particular radioactive isotope is 72 hours.
Write an equation to relate the mass of radioactive material remaining to time (in hours).
----------------------------------------------------------------------
If half life is 72 hours, then
This model then becomes
p, initial quantity
y, final quantity
t, time in hours
You can figure the other questions based on that.
