A project question might be, How does the salinity (salt concentration) of water affect its speciﬁc gravity? Clues for Your Investigation 1. Using the hydrometer made in the original experiment, determine the density of different salt solutions. Make the salt solutions with equal amounts of water but different amounts of salt, such as the solutions shown here in the Speciﬁc Gravity Data table.
