i. Generally, problems based on stoichiometry are of the following types :

  • Problems based on mass-mass relationship 
  • Problems based on mass-volume relationship
  • Problems based on volume-volume relationship.

ii. Steps involved in problems based on stoichiometric calculations :

  • Write down the balanced chemical equation representing the chemical reaction.
  • Write the number of moles and the relative masses or volumes of the reactants and products below the respective formulae.
  • Relative masses or volumes should be calculated from the respective formula mass referring to the condition of STP.
  • Apply the unitary method to calculate the unknown factors) as required by the problem.
