Title: Density of Liquids Lab
Date:
Question: Do liquids have different densities?
Info: Liquid particles are tightly compact, take the shape of the container slip past one another
and have a definite volume. The equation for density is Mass / Volume = Density. Water’s
density is 1g/mL.
Materials: Triple Beam Balance, Graduate, Oil, Salt Water, Corn Syrup, and Rubbing Alcohol.
Prediction: I think_____________will be the most dense liquid, and _________the least dense.

Put on goggles and aprons.
Pick up supplies.
Mass empty graduate. Take data.
Mass graduate with 10 mL Salt Water. Take data.
Subtract empty graduate amount from Mass taken with Salt Water. Take data.
Calculate density. Mass/Volume = Density
Rinse and clean graduate to be ready for next liquid.
Repeat for all liquids

Analysis:
1. Based on your data, which liquid was least dense?
2. Based on your data, which liquid was most dense?
3. Reflect if your data is different than others, don’t change it, but explain why you think it
is. Are these either User or Equipment errors?
4. The word viscous means resists flowing. Which liquid is most viscous?
5. If you were to combine these liquids, predict the order they would layer
themselves based on their density in a test tube.
Draw the tube and label the layers.
6. If you were to add water to the test tube, where would the water settle?
