A sample contains 20 kg of radioactive material. The decay constant of the material is 0.179 per second. If the amount of time that has passed is 300 seconds, how much of the of the original material is still radioactive? Show all work
Answers: 2
kilograms of radioactive material after 300 seconds.
(1)
- Rate of change of the mass of the radioactive material, measured in kilograms per second.
- Current mass of the radioactive material, measured in kilograms.
- Decay constant, measured in 
.
(2)
- Initial mass of the radioactive material, measured in kilograms. 
- Time, measured in seconds.
, 
and 
, then the initial mass of the radioactive material is:
