Law of Conservation of Mass:
The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products. This means that matter is neither created nor destroyed during a chemical reaction, but it can change its form. The law of conservation of mass is a fundamental principle in chemistry and is supported by numerous experimental observations.
Given Information:
- Mass of sodium carbonate (Na2CO3) = 5.3g
- Mass of ethanoic acid (CH3COOH) = 6g
- Mass of carbon dioxide (CO2) produced = 2.2g
- Mass of water (H2O) produced = 0.9g
- Mass of sodium ethanoate (CH3COONa) produced = 8.2g
Evidence of Law of Conservation of Mass:
1. Chemical Equation:
The given reaction can be represented by the balanced chemical equation:
Na2CO3 + 2CH3COOH → 2CH3COONa + H2O + CO2
2. Total Mass of Reactants:
The total mass of the reactants can be calculated by adding the individual masses:
Total mass of reactants = Mass of sodium carbonate + Mass of ethanoic acid
Total mass of reactants = 5.3g + 6g = 11.3g
3. Total Mass of Products:
The total mass of the products can be calculated by adding the individual masses:
Total mass of products = Mass of carbon dioxide + Mass of water + Mass of sodium ethanoate
Total mass of products = 2.2g + 0.9g + 8.2g = 11.3g
4. Comparison of Mass:
The total mass of the reactants (11.3g) is equal to the total mass of the products (11.3g). This confirms that the mass is conserved during the chemical reaction.
Explanation:
According to the law of conservation of mass, the total mass of the reactants must be equal to the total mass of the products in a chemical reaction. In this case, the total mass of the reactants (11.3g) is equal to the total mass of the products (11.3g), as calculated from the given masses.
The balanced chemical equation also supports the conservation of mass. The coefficients in the balanced equation represent the relative number of molecules or moles involved in the reaction. When the equation is balanced, it ensures that the number of atoms on both sides of the equation is the same, which in turn guarantees the conservation of mass.
Therefore, the observations of the reaction, where the total mass of the reactants is equal to the total mass of the products, are in agreement with the law of conservation of mass.

The total mass of the reactants can be calculated by adding the individual masses:
Total mass of reactants = Mass of sodium carbonate + Mass of ethanoic acid
Total mass of reactants = 5.3g + 6g = 11.3g
3. Total Mass of Products:
The total mass of the products can be calculated by adding the individual masses:
Total mass of products = Mass of carbon dioxide + Mass of water + Mass of sodium ethanoate
Total mass of products = 2.2g + 0.9g + 8.2g = 11.3g
4. Comparison of Mass:
The total mass of the reactants (11.3g) is equal to the total mass of the products (11.3g). This confirms that the mass is conserved during the chemical reaction.
Explanation:
According to the law of conservation of mass, the total mass of the reactants must be equal to the total mass of the products in a chemical reaction. In this case, the total mass of the reactants (11.3g) is equal to the total mass of the products (11.3g), as calculated from the given masses.

Therefore, the observations of the reaction, where the total mass of the reactants is equal to the total mass of the products, are in agreement with the law of conservation of mass.
