# Graphical method for calculating density

Calculate the percent error by comparing your densities question 1 to the accepted values. Also if the water does not cover the metal by now start all over with clean samples. If you mess up, start over from step 2 with fresh samples. This is because density can be calculated using the formula: Consider the following problem: A block with a mass of Precise filling to that mark increases reproducibility and data quality. This force will be equal to the weight of the displaced fluid.

Also, we measured their volume by using a cylinder with distilled water, then we have measured the volume, and then we put in the metal and recorded the total volumes.

## How to make a density graph

You must use the correct calibration result with the appropriate data. This force will be equal to the weight of the displaced fluid. Also make sure that the pellets are all completely immersed in the water. To determine roughly how dense an object is, place it in various fluids of known density and observe the result. In this lab, did you determine the mean, median, or mode for the density? Analysis: Subtract the mass of the empty cylinder from each combined mass measurement to obtain three mass measurements of water. Show all your work. It sharpened my knowledge about the water displacement method.

Estimated Density using Archimedes Principle.

## Density graph worksheet

Record the ID Code of the unknown solid on your report form. How does the instrument error compare to standard deviation error? Do you think density could help identify an unknown substance? Calculate the percent error by comparing your densities question 1 to the accepted values. Record your final volume. Subtracting the initial volume of water from the final volume of water Their density cannot be found using a ruler and a geometric formula. Press enter to begin your search Graphical Method for Calculating Density No Comments Class data will be used so as to include multiple trials. Look up the accepted values for the density of Aluminum and Iron.

Error Analysis Well, I already did the percent error in my calculations, but there is one error of analysis. When finished, retrieve and dry the aluminum pellets and return them to your instructor.
