➝ According to law of constant proportion, a chemical compound always consist of the same element combine together in the same proportion by mass or by volume.for example Ratio of $\rm\:H_2O$ by mass will be 1 : 8 and ratio of $\rm\:H_2O$ by volume will be 2 : 1.

• It was given by Joseph Proust in 1779.
• It is also called fixed propotion

⤇ Law of conservation of mass :-The law of conservation of mass state that during a chemical reaction matter is neither create or nor destroy.It means that mechanical reaction process the total mass of the product is equal to the total mass of reactants.

⤇ Atom is the smallest particles of an element that can take part in a chemical reaction.

⤇ Atoms are very very small in size 3 × 10⁷ copper atoms arrange end to end in a line would cover a distance of only 1 cm.
