the density of a liquid that has mass of 7.5E3 mg and a volume of 22.01mL??
Density=Mass/Vol
In this problem Mass=7.5E3mg=7.5 gm
Volume=22.01 ml
Density of Liquid=7.5/22.01=0.34075 gm/ml

A student performed a series of measurements (volume/mass) of an unknown liquid in order to determine its density. Using a graduated cylinder, the student added an amount of unknown liquid to the graduated cylinder, then recorded the mass and volume of the liquid. The student repeated the process several times, adding more liquid each time and recording the mass and volume. The student plotted the data (mass on y-axis, volume on x-axis). The resulting data table and graph looked like...
