Law of Conservation of Mass Formula And Sample Example

Law of Conservation of Mass Formula :

Law of conservation of mass δ ρ(m/V) in meter per volume and divided by the δ t(s) in second  and addition is  the divergence ∇( ρ(m/v) in meter per volume and multiply the velocity V(m/s) in meter per second is equal to the zero. Hence the law of conservation of mass formula can be written as

δ ρ(m/V) / δ t(s) + ∇( ρ(m/v)* V(m/s)) =0

Where,

Ρ → density in m/v

T → time in second

V → velocity in m/s

∇ → divergence

Sample Example :

Example 1:

Calculate the reaction in terms of law of conservation of mass? In a 20 grams of calcium carbonate (caco3)produces 4.8 grams of carbon dioxide (co2) and 5.5 grams of calcium oxide (cao).

Answer:

According to law of conservation of mass

Mass of reactants =Mass of products

20 gram of caco3=4.8 grams of co2+5.5 grams of cao

20gram of reactant =20 grams of products

Hence it is proved that the law of conservation of mass is followed by the above reaction

Example 2:

Calculate the reaction in terms of law of conservation of mass? In a 80 grams of calcium carbonate (caco3)produces 3.8 grams of carbon dioxide (co2) and 4.5 grams of calcium oxide (cao).

Answer:

According to law of conservation of mass

Mass of reactants =Mass of products

80 gram of caco3=3.8 grams of co2+4.5 grams of cao

80gram of reactant =80 grams of products

Hence it is proved that the law of conservation of mass is followed by the above reaction
