Find the mass of this ion moving in a magnetic field

Click For Summary
SUMMARY

The discussion centers on calculating the mass of an ion moving in a magnetic field by equating magnetic force to centripetal force. The conclusion identifies nitrogen as the ion in question, with a molar mass of 14 grams per mole. The participant confirmed their method was correct after resolving discrepancies in their calculations. This approach effectively demonstrates the application of physics principles to determine atomic mass.

PREREQUISITES
  • Understanding of magnetic force and centripetal force equations
  • Basic knowledge of ion properties and molar mass
  • Familiarity with unit conversions in chemistry
  • Proficiency in using scientific calculators for physics calculations
NEXT STEPS
  • Study the relationship between magnetic fields and charged particle motion
  • Explore the principles of centripetal force in different contexts
  • Learn about the periodic table and molar mass calculations
  • Investigate common errors in scientific calculations and how to avoid them
USEFUL FOR

Students in physics and chemistry, educators teaching ion behavior in magnetic fields, and anyone interested in the practical applications of physical laws in determining atomic properties.

I had started off by equating the magnetic force to the centripetal force, to find the mass of a single ion. Then calculated the mass of what 1 mole of that ion would weigh to identify what the ion is

Hence the answer would be nitrogen (option C) as 1 mole of nitrogen weighs 14g
Would this be the right way of going about it?

Thanks for any help!

Ok thank you, was getting different values beforehand but I believe I must have type the numbers in incorrectly into the calculator
