SUMMARY

This discussion centers on solving a radioactive decay exercise from the Virtual Dating courseware. The user provided several answers, including 1200, 2100, 3800, 14500, 1125, and 2050, but struggled with the seventh answer, initially guessing 3775 and later arriving at 4175, which was incorrect. The correct answer for the seventh question is confirmed to be 4200. This highlights the importance of understanding the decay formula and calculations involved in radioactive decay problems.

PREREQUISITES
  • Understanding of radioactive decay concepts
  • Familiarity with decay formulas and calculations
  • Basic knowledge of half-life and its application
  • Ability to interpret scientific exercises and data
NEXT STEPS
  • Review radioactive decay formulas and calculations
  • Study half-life concepts and their applications in real-world scenarios
  • Practice solving similar radioactive decay exercises
  • Explore online resources or courses on nuclear chemistry
USEFUL FOR

Students studying nuclear chemistry, educators teaching radioactive decay, and anyone needing assistance with scientific exercises related to decay calculations.

Total Frustration!Radioactive Decay!Need Fast Help!

Hello,

I have the link to the exercise:
http://www.sciencecourseware.org/VirtualDating/files/RC_6.php"

Here are my answers:

1. 1200
2. 2100
3.3800
4.14500
5.1125
6. 2050
7. ?

I would think (7) would be 3775, but it's not. I have been trying this for hours and cannot figure this out, please help. My head hurts...
