The law of conservation of mass states that

In any chemical reaction mass is neither created nor destroyed rather it remains conserved

  • Mass of reactants=Mass of products

Look the chemical reaction below

[tex]\\ \sf\longmapsto 2H_2+O_2=2H_2O[/tex]

Count the mass on both sides and simplify

  • It will be 18g and ratio remains one
