Explanation:
The law of conservation of mass states that mass is conserved which also means that it cannot be created or destroyed within the isolated system.
We can add the mass of the reactant and can be equal to the mass of the product. But in some cases, it will not work like:
If reactants are not in the mole ratio, there will be a limiting reagent.
If a gas is one of reactants or products.
Radioactive decay and nuclear reactions(fission or fusion).
The density is the ratio of the substance's mass to its volume. Density is an extensive property even though mass and volume are both intensive properties. It is because density is constant for each substance at a specified temperature and pressure. The equation is
Density = mass/volume
Substituting the values,
1.40 g/cm³ = [500 mg * (1 g/1000 mg)](Volume)
Volume = 0.357 cm³
Answer: The correct answer would be : True
I hope that this helps you !
