Explanation
Density is calculated using the formula: Density = Mass/Volume. Here, the mass of salt is 25 grams and the volume of water is 250 mL. Adding the mass of salt to the volume of water gives the total mass of the solution. However, for simplicity, we can assume the volume of the solution remains approximately 250 mL.
