Learning Objective: I can measure the mass and volume of and object in order to determine its density.

Density & Properties of Water Work Packet - worth 30 points

Notes (to write down at the top of page 1 of packet):

density - the ratio of the mass of a substance to its volume; can be used to test a substance's purity
Density Triangle:
density=m/v
mass=d x v
volume=m/d

Page 1 #4 Hint: To solve for the mass of the flask filled with acetone, you first have to figure out the mass of the water that was in the flask (mass with water - mass empty = mass of water). Then use the density of water (1.0g/mL) to find the volume of acetone, and the mass of acetone. Finally find the mass of the flask+acetone.
