Important Calculation

Post by Admin on Fri Sep 03, 2010 10:41 am

Important calculation in chemistry SPM

  1. mole
  2. mass
  3. volume of gas
  4. Determine empirical formula & molecular formula
  5. no of particles(atom/molecule/ion)
  6. concentration(involve dilution)
  7. rate of reaction
  8. heat of neutralization
  9. heat of displacement
  10. heat of precipitation
  11. heat of combustion

Attached file is my powerpoint showing everything related to the moles. Hope it will help.

Some tips:

  1. Understand the above concepts first
  2. Understand the relationship
  3. Practice makes perfect
