#### Answer

Taking the ratio for the first sample, we get 14.1 g/L; for the second sample, we get 14.0 g/L. For the third sample, we get: 14.0 g/L,. For the fourth sample, we get: 14.1 g/L.
The ratios clearly depict that the ratio of mass to volume for each experiment is the same, which is also known as constant.
