The radioactive isotope uranium-232 has a half-life of 68.9 years.
The decay constant of uranium-232 is
If you have 35 grams of uranium-232 to begin with, the equation that describes the radioactive decay is
Help please!
Recall that where (interchangeable with ) is the half life, and is the decay constant. Thus,
Now that we have , we can set up our equation.If you have 35 grams of uranium-232 to begin with, the equation that describes the radioactive decay is
Help please!
The decay equation has the form , where is the initial amount of the substance.
Thus, our decay equation is
