A solid and liquid have the same mass if the amount is the same.

Generally, a solid is denser and heavier than the same substance in a liquid state due to the arrangement of molecules being more compact in solids. However, the mass remains the same regardless of the state of matter, as mass is a measure of the amount of matter in an object.
Yes, mass is conserved when a solid is dissolved in a liquid. The total mass of the solid and the liquid remains the same before and after dissolution. The solid particles disperse in the liquid, maintaining the overall mass of the system.

The mass of the water remains the same when it changes from solid to liquid. The only difference is in the arrangement of the molecules as they transition from a fixed crystalline structure in solid form to a more fluid and mobile arrangement in liquid form.
Liquid density is a measure of how much mass a liquid has in a given volume. It is calculated by dividing the mass of the liquid by its volume. The density of a liquid is typically expressed in units such as grams per milliliter (g/mL) or kilograms per liter (kg/L).
In a chemical reaction, the total mass of the reactants will always be equal to the total mass of the products (law of conservation of mass). Therefore, the mass of the substance in any state (solid, liquid, or gas) will remain the same before and after the reaction.
