Salt Water Samples Salinity Analysis

Which sample has the greatest volume of water?

Final answer: Sample 2 has the greatest volume of water.

Understanding Salinity in Salt Water Samples

In this question, we are given the salinity of four samples of salt water, measured in parts per thousand (ppt). The salinity represents the amount of salt dissolved in each sample. Sample 1 has a salinity of 4.2 ppt, Sample 2 has a salinity of 6.7 ppt, Sample 3 has a salinity of 3.5 ppt, and Sample 4 has a salinity of 2.9 ppt. Each sample was made by dissolving 0.2 grams of salt in water. To determine which sample has the greatest volume of water, we can compare the salinity values. The higher the salinity, the more salt is dissolved in the water, and therefore, the less water there is in the sample. Therefore, the sample with the lowest salinity, which is Sample 2 with a salinity of 6.7 ppt, will have the greatest volume of water. The answer is Sample 2.
