Calculate the density of the metal cylinder using the cylinder dimensions and the formulafor the volume of a regularcylinder. Chemistry 101 Lab 1: Measurement andDensity Objectives: a. As best as you can, draw 10 mLof distilled water into the 10 mL volumetric pipet with the suction device andthen expel that volume into the small beaker. To calculate the specific gravities of solids and liquids d. For instance cold water is denser than warm water; ice is less dense than both. Explain the relationship of the variables as presented by the data.

The density of water is 1, so in order to keep the film container from sinking, the density of the sand-filled film container must be less than 1. The density of the liquid in the beaker can be adjusted, and a variety of objects can be studied during the investigation. The difference between these two measures is the volume of the metalcylinder. One way to do this is to mentally compare your answer against the density of water 1 gram per cubic centimeter. Weigh and record the mass ofthe glassware plus water for each item. The number of significant figures will be the same as the number in your least precise value.

Density is the compactness of a substance. This was done by Raman Pfaff. PartTwo — the density of a metal 6. When using the 50ml cylinder, I filled it with. Two small rocks were obtained that differed in size by roughly half. Then, consider relationships involving the mass and volume to try to predict the sinking or floating.

Remove and dry the metal cylinder and return it tothe lab cart. If you would like more information, please contact me at. To calculate the volume of a rectangular object and to express the volume in volume metric units e. Determine their mass using a balance. This volume was recorded and the rocks were then added to the water one at a time with the increase in volume being recorded after each one. Which method is more accurate , using the cylinder dimensions or waterdisplacement? Measure, as accurately as possible, 50.

Explain any trends in the data that will be used. I'll add more of a challenge to this when I find time. Procedure: a The density of metals First I obtained a quantity of unknown metal. It is possible to find the density of an object be it liquid, gas or solid by the use of only a select few measurements and the formulae contained herein. Hint: This should not be the same reason as the one you gave in question 7. So, if you have four significant digits for mass but only three significant digits for volume, your density should be reported using three significant figures.

Density is not a property that depends upon the amount of substance present. Clearly, you should enter this information into the data table, 2 ndto last line, but show the details of one such calculation. The dependent variables are the mass and if the film container floats or sinks. New York: The Macmillian Company, 1920. Upper Saddle River: Pearson Education, Inc. Weigh and record the mass and letter of a metalcylinder. Calculate the volume of the metal V m.
