Question

Part 1: Volume and Density Measurements (Liquid) 1 Gather the graduated cylinder, distilled water, short stem pipet, and isopropyl alcohol. 2 Place the clean, dry, 25 ml graduated cylinder on the tared scale. Record the mass of the graduated cylinder (g), in Data Table 3 Fill the graduated cylinder with 5.0 mL of distilled water by using the short stem pipet to add water dropwise until the minuscus in the graduated cylinder reads 5.0 mL. Record the volume in Data Table 4. 4 Place the 25 mL graduated cylinder with 5.0 mL distilled water on the tared scale. Record the mass of the graduated cylinder and the liquid in Data Table 4. 5 Calculate the mass of the water by subtracting "Mass A" from "Mass B." Record the mass of the water in Data Table 4. 6 Dispose of the water and fully dry the graduated cylinder. 7 Repeat steps 2–6 for isopropyl alcohol. 8 Calculate the densities of both the water and the isopropyl alcohol and record in Data Table 4. Note: The accepted value for the density of water is 1.00 g/mL and the accepted density for isopropyl alcohol is 0.786 g/mL. 9 Determine the percent error, using the equation below, between your calculated densities and the accepted values for both water and isopropyl alcohol. experimental density - accepted density Percent error(%) = 10 accepted density X 100%

I need the density (g/mL) for the water column and the isopropyl alcohol column. With math shown and included please! The question requires me to show work. If possible, I would also like the percent error's (with work shown) of the water and isopropyl alcohol columns. Thank you!

Answer 1

For water mass of liquid (Watu) = 4.79 volume of water = 5.om we know that density = mas Volume density - 4.73 Some = 0.949 mu so density g water calculated = 0.94 (acepled) literature value y density of watu = 1.00 opo percent error = | experimental density – aceepted density) accepres density = 0.94 -1.00] = 6oo Answer - Xloo For isopropyl alocher man of liquid (isopropyl alochol) = 3.9g Volume of water = soomu density = man = 3.9g = 0.789 density = volume some density g iso propyl alochot ( experimental) 20.78 .. 7 = 0.78 – 078 - 0.78 = 0.6% Answer
