Concept introduction:

  • Balanced chemical equation of a reaction is written according to law of conservation of mass.
  • Equation for Number of moles of a substance, from its given mass is,

Number of moles=GivenmassMolecularmass

  • Equation for Number of grams of a substance from its number of moles is,

Number of moles×Molecularmass in grams=Numberofgrams

  • Mole ratio between the reactant and a product of a reaction are depends upon the coefficients of reactant and product in a balanced chemical equation.
