SUMMARY

The discussion focuses on calculating the mass defect of the cobalt isotope 5927Co, with an atomic mass of 58.933198 u. The correct mass defect in kilograms is established as 8.999737e-28 Kg. The user attempted to convert this value to Atomic Mass Units (AMU) using the conversion factor of 1 amu = 1.6605e-27 Kg, arriving at a result of 0.5419895815 amu. However, this answer was not accepted by Webassign, indicating a potential error in the conversion process.

PREREQUISITES
  • Understanding of atomic mass units (AMU)
  • Familiarity with mass defect calculations
  • Knowledge of unit conversion techniques
  • Basic proficiency in scientific notation
NEXT STEPS
  • Review the concept of mass defect in nuclear physics
  • Learn about unit conversion methods, specifically for AMU and Kg
  • Explore the use of scientific calculators for unit conversions
  • Investigate common pitfalls in using online homework platforms like Webassign
USEFUL FOR

Students in physics or chemistry courses, educators teaching nuclear physics concepts, and anyone involved in atomic mass calculations or unit conversions.

Homework Statement


Determine the mass defect of the nucleus for cobalt 5927Co, which has an atomic mass of 58.933 198 u. Express your answer in AMU and Kg.

Homework Equations


How do I get the AMU? Or Atomic Mass Unit?

The Attempt at a Solution


Ok, so I solved the answer in Kg. The answer in Kg is 8.999737e-28 Kg (This answer is correct). And I need to provide the answer in Atomic Mass Units also. I know the conversion factor is 1 amu = 1.6605e-27 Kg. My answer is .5419895815, but Webassign is not accepting the answer. Please help.

I don't have a calculator near to me at the moment but all you need to do is divide your answer by 1.6605e-27 to get the units in amu
 
The number i plugged into webassign is the Kg divided by the conversion factor...
