DENSITY. 1.A substance has a volume of 2.0 cm₃ and a mass of 38.6 g. What is the density? 2.If 17g of brass occupy 2 cubic centimeters, what is the density?

To find the density 1- Find the mass of the object 2- Find the volume of the object 3- Divide Density = Mass Volume.

If objects are the same size they will have the same density. Different materials have different densities. Density is made up of two other measurements.

Examples: Olive oil has 0.85 g / cm 3 (or 0.85 g / mL). 1 mL of olive oil has a mass of 0.85 grams. Iron has 7.8 g / cm 3. 1 cm 3 of iron has a mass of.

Presentation transcript:

Some guidelines… You will be finding the density of two different substances – one solid and one liquid (DI water). You will need to take multiple trials of different amounts/sizes of your substance. Make sure that you are using the same substance for each trial! Data should be in a data table. We will graph it tomorrow. You are free to use any of the equipment on the cart. If you want to use something that is not there, ask me and I’ll get it.

Analysis Graph your data for both substances. Use the best graphing practices as a reference! Find the slope of both graphs. Use the given data table to identify your solid. Find the percent error of your experiment using the following formula: Write a RERUN conclusion
