The chart below shows the percent change in mass of eggs in various salt solutions over a 1 hr period. By looking at the trajectory of the lines, you can tell if there was more or less salt in the egg in comparison to the solution based on whether water move out (it decreased in mass), or if water moved in (it gained mass). Based on the diagram, what percentage of salt is closest to the salt concentration in the egg, given the various lines for each percentage solution the egg was placed into?
