Purpose and Method
Things to think about:
What is the goal of this experiment? Explain how it is accomplished.
What is the general method (not step by step detailed procedure) that you will be using to achieve this goal? How will you
process the data that you record in lab? (What calculations will you use and how do you obtain all of the values to plug into
those equations?)
(5 points)
The purpose of this experiment is to use different methods to find the volume of water at a given density and dependent on the mass of
the water.
It is accomplished by either using a graduated cylinder, a buret, or a pipet.
Using each glassware my lab partner and I will try
to measure every trial of water as close as we could.
After using finding the volumes of water, we will then use what we had learned
