The graph shows the average mass of containers filled with water, NACI, and MgSO4 over a 16-day period. The mass of water decreases until day 12 and then remains constant. The mass of NACI decreases from day 2 to day 16. The mass of MgSO4 also decreases initially but becomes constant from day 12. In summary, all three substances decrease in mass as the days go by. In the graph, it shows the average mass of container on water, NACI, and MgSO4 for 16 days. Water decreases as day goes and stops decreasing from day 12 and NACI decreases from day 2 to day 16. MgSO4 also decreases from day 1 but stops and maintains the same mass of the container since day 12. Overall, they all decrease as days go.
