Detailed explanation-1: -Salt water is more dense than pure water because the salt in it contributes to the mass of the entire solution. Given equal parts salt water and pure water, the salt water will be more massive; therefore, salt water is more dense than pure water.
Detailed explanation-2: -1 molar aqueous solution is more concentrated than 1 molar aqueous solution because 1 molar solution contain 1 mole of solute in 1 litre of the solution which include both solute and solvent. So, the mass of solvent (i.e. water) is less than 1000 gram.
Detailed explanation-3: -The USGS salinity scale defines three levels of saline water. The salt concentration in slightly saline water is 1, 000 to 3, 000 ppm (0.1–0.3%); in moderately saline water is 3, 000 to 10, 000 ppm (0.3–1%); and in highly saline water is 10, 000 to 35, 000 ppm (1–3.5%).
Detailed explanation-4: -The water, being in the greater quantity, acts as the solvent. The salt quickly dissolves in the solvent forming a dilute salt water solution. The term “dilute solution” means that a relatively small amount of solute has been dissolved in a lot of solvent.
