Sagot :

In a chemical reaction, the Law of Conservation of Mass states that the mass of the reactants is equal to the mass of the products. This means that during a chemical reaction, mass is neither created nor destroyed; it is conserved.

Given that the mass of the products is measured to be \(120 \, \text{g}\), according to the Law of Conservation of Mass, the mass of the reactants must also be:

[tex]\[ \text{Mass of reactants} = \text{Mass of products} \][/tex]

Since the mass of the products is given as \(120 \, \text{g}\), the mass of the reactants must be:

[tex]\[ \text{Mass of reactants} = 120 \, \text{g} \][/tex]

Therefore, the correct answer is:

[tex]\[ 120 \, \text{g} \][/tex]
