Final answer:
The relationship between the density and mass percent of a solution is linear. As the mass percent increases, the density of the solution also increases.
Step-by-step explanation:
The relationship between the density and mass percent of a solution is linear. The density of a solution refers to the mass of the solvent or solute present per unit volume. Mass percent, on the other hand, represents the proportion of the solute's mass in the total mass of the solution.
When the mass percent of a solute in a solution increases, the density of the solution also increases. This is because a higher concentration of solute particles leads to greater mass per unit volume, resulting in a denser solution.
Thus, the relationship between density and mass percent is directly proportional, which can be represented by a linear equation.
