A. Purpose The purpose of this lab was to practice measuring the mass and volume of different samples and to calculate the density and specific gravity of those samples using the measurements.
B. Equipment
1. Electronic balance- The electronic balance is a device used to measure the exact mass of an object
2. Graduated cylinder- The graduated cylinder is a tool used to measure the volume of a liquid
3. Pipets- Pipets are small tubes that suck up and contain liquids
C. Technique
1. The water displacement technique is used to measure the volume of a solid object using a graduated cylinder and water. This works by filling up a graduated cylinder about halfway with water and then measuring the volume by looking at the lowest

C. Quantitative
Solid Data Table Solid 1 Solid 2
Mass of solid (g) 18.35 49.57
Water volume at start (mL) 31.3 29.2
Water volume after solid is added (mL) 37.9 35.7
Volume of solid (mL) 6.6 6.5
Density of solid
(g/mL) 2.78 7.63
Specific gravity of solid 2.73 7.48
II. Computations
A. Volume of water displaced (Solid 1) Water volume with solid - Water volume at start = Volume of solid 37.9mL – 31.3 mL = 6.6 mL
B. Density = Mass/ Volume
1. H20 5.40g/5.32 mL= 1.02g/mL
2. Vegetable Oil 4.98g/5.21mL= 0.956g/mL
3. Solid 1 18.35g/6.6mL= 2.78g/mL C. Specific gravity = density of substance/ density of standard (water)
1. Vegetable
Both of the liquid samples, vegetable oil and mineral oil, would float on water, whereas both solids one and two would not. The liquids would float on water because their densities are smaller than that of water and therefore water would sink to the bottom. Meanwhile, both of the solids have densities that are higher than water and therefore the solids would sink.
2. If you wanted to make layers of four liquids in a graduated cylinder you would have to put them in from highest density to lowest density because the higher the density the closer it will be to the bottom of your graduated cylinder.
3. Specific Gravity has no units, unlike density. In the calculation for specific gravity both of the units cancel each other out. Working with specific gravity would be different from working with density because there are no units to cancel out or to

- Each liquid that was used in Part I has its own independent density. Density being the relationship between the mass and volume of a substance. In this portion of the lab we explored relative density, each liquid compared to the others. The corn syrup was the most dense, in comparison to the other liquids. Whereas the vegetable oil was the least dense compared to the other liquids. The liquids in between followed this same principle in their respective orders.…

The density column is constructed with the liquid consisting of the greatest density at the bottom to the least dense liquid. By utilizing the density column, a range of density for solids may be determined. Saturated Potassium Bromide is poured first, then Glycerol, then water, and finally vegetable oil on top, which is least dense. When the iron particle is dropped into the density column, it fell to the bottom; thus, results show iron has a density greater than 1.34 g/mL, which is the Potassium Bromide solution’s density. The rubber cork also fell to the bottom, showing that it has a density greater than 1.34 g/mL. When the cork is dropped into liquid, it floats on top of the vegetable oil, proving it has a density less than 0.93 g/mL…

When doing the lab we were introduced to two ways of finding density, one commonly used in algebra, and the other not as common. The first step to find density is finding the volume by using (length x width x height). This way is the most used way to find volume because most kids are familiar with it. The other way is water displacement. If you have a beaker of water then you look at eye level to see what the initial volume is and then drop the substance in the water and then that gives you the final volume. Once you have that then you subtract the final by the initial to get the volume. I myself like water displacement because it is more interesting and I am not very good with algebra. Now after you have fond the density, you can identify it by its physical property. Physical property is a characteristic of a substance that does not involve a chemical change such as density color or hardness. For instance a aluminum cube can be described as: solid, sliver, cube, and hard.…
