I subtracted the intial amount of liquid in the buret from the final amount of liquid in the buret. He scrapbooks yonder every minute or three. I simply subtracted the mass of the empty flask and rubber stopper from the mass of the full flask and rubber stopper.

A precision of For example, the precision for the water was found by this equation: This academia was first published 25 Sep and last revised 13 Feb To find the average density, I added the three densities I found, then divided that total by three to find the average.

My precision was 1. My data from the unknown substance turned out incredibly well. A few drops of the liquid inside seemed to drip out from right above the bottom where it was supposed to come out. My accuracy was very high, but my precision was not quite as good.

Precision was found by taking the absolute value of the highest density minus the lowest density, dividing that difference by the average density, and then multiplying that answer by Therefore, I should be even closer to the actual density.

This difference was how much liquid was dispensed. However, my accuracy turned out to be very high, as my error was very low. Some of my error can be accounted for by a leak in my buret. The equation for the water was 0. This gave me an answer of In the end, my data was fairly accurate with the actual data, so the experment was a success.

This same method was used to find the volume of water in the flask. A sample equation would be An example would be Finally to find the error, I found the absoulte value of my measured density minus the actual density.

In order to find the density, I simply divided the mass found by the volume found. My accuracy was also high, as my error was only 0. Also, I may have gotten finger prints on the flask, which would have added a slight bit of extra weight that could throw my calculations off.

I assume 0 ppt would be perfect precision, so 1. With my data, my equation for the water was 0.Lab Report on Density Measurement Essay INTRODUCTION Background of the Experiment Mass density describes how heavy an object is. Defined by the Greek letter ρ, read as rho, density is a basic yet important physical property of matter.

experiment date(s): 1 Experiment 1 - Density of Liquids and Solids Goal: To accurately determine the density of an unknown liquid and an unknown solid. Density = mass units are: g or g where 1 mL = 1 cm3 volume mL cm3 To properly measure density, we need a container whose volume is known to a high degree of.

report your result to the correct number of significant figures. 3) 3The value of the slope obtained above in #2 yields the density of your unknown solid, in units of g/cm. Using this value, identify your unknown solid (see Procedure, Part C, #5).

The task for our lab was to determine the density of water and compare our recordings to the actual density of water listed in our lab packet. Then we were to find the density of an unknown liquid and find out what the substance was by matching its density with densities of substances listed in our packet.

Lab 1. How Can the Density of a Substance be Determined “Materials and Methods” section of your lab 1 report.

These procedures will serve as a starting point. In class you and your lab partners will compare each other's methodologies, develop a For liquids and solids the mass is usually expressed in grams (g) and the volume in.

Density of Water Lab Conclusion Density is a measure of how much matter, or mass(m), takes up a certain amount of space, or volume(v). The formula for density is D=m/v or density equals mass divided /5(3).
