1.	How to use stochiometric calculation explain briefly
Answer» Stoichiometric Calculations are mostly based on chemical formulas.\tFormula Mass: It is defined as the sum of the atomic weights of the each atom present in the molecule of the substance. For example formula mass of Na2S is calculated as 2(23) + 1(32) = 78\tAvogadro number: Avogadro’s number is defined as the number of particles present in one mole of substance. It is defined as a number of atoms present in exactly 12g of C-12.Avogadro number is valued as 022× 1023\xa0\tMolar Mass: It is defined as the sum of the total mass of all the atoms that make up a molecule per mole.
