# A volume of saline solution weighed 25.6 g at 4 degrees C. An equal volume of water at the same temperature weighed 24.5 g. what is the density of the saline solution?

##### 2 Answers

The density of the saline solution is 1.045 g/mL.

The density of pure water is 1.000 g/mL.

Since the volumes are the same, and the saline solution has more mass,

The density of the saline solution is

Pure water is at its most dense at

Since the volume of the water is the same as the volume of the saline solution, we now know the mass and volume of the saline solution and can calculate its density.
