Density of rubber stopper. 14g 7 cm3 2 g cm3. Calculate the density of the rubber stopper. The density of the stoppers were all different but they were very close to each other. 7 stopper fits standard 3 5 and 6 5 gallon glass carboys 10 stopper fits standard 3 5 and 6 gallon plastic carboys 11 stopper fits demi johns 14 25 gallon glass carboys.
Volume of the rubber stopper we had to use water displacement. I was surprised to see that the density of water did calculate out to be exactly 1 g ml. Calculate the density of the unknown solid. Experimental weight 161n volume 3 38 ml.
Calculations on graph the slope of the relationship between mass and volume is 1 08g ml. The difference in the two volumes was the volume of the rubber stopper. Obtain a rectangular solid and record the unknown number in the data table. The average density of the rubber stoppers was 1 076g ml.
Density of inorganic sodium salts in water is plotted as function of wt mol kg water and mol l solution. A rubber stopper has a mass of 7 452g and displaces 6 0ml of water in a graduated cylinder. Density of an unknown solid 1. Weigh the unknown solid and record the mass.
Density of acetic acid citric acid formic acid d lactic acid oxalic acid and trichloroacetic acid in water. Density of aqueous solutions of organic acids changes in density of aqueous solutions with changes in concentration at 20 c. We measured the volume of water in a graduated cylinder placed the stopper in the cylinder and measured the new volume. Irregular shaped object 1pt 1 51 15 75 reference data.
Calculate the density of the rubber stopper for each trial and report the average value for both trials. Use the experimental weight and volume of the rubber stopper to calculate the density of the stopper in kg m3 using the equation ρ m v. An unknown rectangular solid has a mass of 140 417g and measures 5 05cm by 2 50cm by 1 25cm. To solve for density take mass divided by volume.
