Specific gravity is a dimensionless unit also known as relative density. It divides the density of the substance of interest by the density of water at a specific temperature. Specific gravity is generally used to help identify an unknown substance because every substance has a particular specific gravity at 20 degrees Celsius.
Specific gravity = density substance / density of water
We have to take into account the change in density of water and ethylbenzene to plot the changes in specific gravity with changes in temperature. Water's density drops as its temperature is raised. To determine ethylbenzene's density, divide its mass at a specific temperature by its volume at this temperature (D=M/V). To determine its specific gravity, make sure to divide the new density of ethylbenzene by the density of water at this temperature.
Ethylbenzene is considered to be a dangerous substance. It is a suspected embryotoxin and teratogen. It is a skin, lung and eye irritant. Avoid this substance while pregnant. Do not inhale its vapor or get this substance on your skin. Always wear proper safety equipment when handling chemicals and work in a fume hood. Ethylbenzene is extremely flammable so avoid open flames when working with this substance.
