Experiment 4: DENSITY

Data Collection and Results Pages Name: (Show work for all calculations.) Date:

I. Density of Water

Room Temp:

Correct Density of Water at this Temp:

Reference:

Calculate the density of water for each trial:

Trial 1: Trial 2:

Calculate the Average Density of Water: Note: The average value cannot have more precision than the individual values. As a rule of thumb, the average should have the same decimal places as the individual values.

Calculate the Error in the Average Density: (Watch your sign and sig. fig.!)

Calculate the % Error in the Average Density: (Watch your sign and sig. fig.!)
