2. LAB: Calculate the Density of Water Mass _____ = DENSITY Volume What is the formula for Density?

3. What instrument is used to calculate mass?  The balance

4. What instrument is used to calculate the volume of a liquid?  The Graduated Cylinder

5. Example of Calculating Density Mass _____ = DENSITY Volume So, if you calculate the mass of substance to be 10 grams, And you calculate its volume to be 5 ml, Then what is its density?

6. Example of Calculating Density Mass _____ = DENSITY Volume 10 grams _____ = 5 grams/mL = DENSITY 5 mL

7. Example of Calculating Density (2) Mass _____ = DENSITY Volume If you calculate the mass of substance to be 4 grams, Then you calculate its volume to be 8 ml, What is its density?

8. Example of Calculating Density Mass _____ = DENSITY Volume 4 grams _____ =.5 grams/mL = DENSITY 8 mL

9. In our lab today …  Each group will be given a different volume of water to work with (Either 10 mL, 20 mL, 30 mL)  Then each group will use the graduated cylinder to correctly obtain & measure their water  Then each group will calculate the density of their sample of water using the “balance”

10. In our lab today …  Each individual must answer the questions on the lab, filling in all the blanks  This lab will be due on Tuesday!  So if you have any questions about the “write-up” over the weekend, be sure to ask on Monday!  Are there any questions?
