Calculate the density of the water by dividing the weight of the water (mass) by its volume and record this value in the data table provided. Experiment 7: DENSITY OF A MARBLE BY WATER DISPLACEMENT * You need: Graduated cylinder, electric scales, marble and water. 1. Fill a graduated cylinder with exactly 50ml of water (this is your initial reading). 2.
Density Lab Report Objective: To measure the density of different materials. Materials: 400 mL Beaker Ruler Water Triple Beam Balance Box of Density Cubes Goggles Tongs Procedure: 1. Put on all safety equipment and gather all materials. 2. Create a chart (A) in your data section with three columns.
[5] Part II – Viscosity The diameter and weight of five of the test spheres were measured and then the volume and density of each sphere were computed. Each sphere was dropped into the cylinder of each liquid and the time it takes for the sphere to fall a certain distance was measured (between the two labels on the cylinder). The distances between the labels were measured. The distance divided by the measured time gives the terminal velocity of the sphere. The measurements of the five spheres were repeated whose diameters and weights were determined earlier and the average of results were calculated.
Carefully determine the mass of the Copper(II) Sulfate, crucible, and lid. 8. Obtain the accepted percent (by mass) composition of water. Pre-Lab Questions 1. Hydrates are crystal solids and water.
Allow the mixture to cool for a few minutes then filter it, using either gravity or vacuum filtration. (We shall be using vacuum filtration.) Wash the residue in the funnel once with a little water and collect all the filtrate. 4. Pour all the filtrate and washings into a 250cm3 volumetric flask.

Follow-Up Questions (Show all calculations) Part I (Each question is worth 10 points.) 1. Convert the length and height measurements for the packet that contains the aluminum shot from units of cm to units of mm using the unit-factor method.
Record the mass of the plasticine. 4. Take a measuring cylinder and fill it with 120 cm3 of water. 5. Now, take the same piece of plasticine tied with thread and immerse it into the measuring cylinder filled with water, by holding the thread.
Measuring Specific Heat for Metals Objectives: 1. Hypothesize about the properties of the metal tested and/or the energy transferred. 2. Calculate the specific heat of the metal using your mass and temperature data. 3.
Lab Report on Boyle's Law: Pressure-Volume Relationship in Gasses Object: The object of this lab is to determine the relationship between the pressure and volume of a confined gas. This relationship is shown by Boyle's law. Procedure: Hook up the pressure sensor Calibrate the pressure sensor. First, open the side arm and record as 1 atm. Next, put the plunger at 5mL.
