Question
Given: ruler 11.56 g, small washer 1.85 g each, large washer 24.30g each
Use the data in Data Tables 4 and 5 to experimentally determine the mass of your ruler. Use one of your 2 trials with 1 small washer at 0 cm, one of your 2 trials with 2 small washers at 0 cm, and one of your 2 trials with 3 small washers at 0 cm to find three experimental values for the mass of the ruler.
How do you experimentalls determine the mass?
