Question

Experiment D: Densities of Solids Purpose: To determine the densities of a rectangular solid and a solid sphere and express the answers in g/cm. To identify each solid. Use the same rectangular solid (as in Expt. B) and the same solid sphere (as in Expt. C). Turn the balance on and press the Tare button to zero the balance. Make sure the display on the balance reads in grams (g). Place each solid on the balance and determine the mass of each. Record answers to the nearest hundredth of a gram. If the sphere doesn't stay on the balance, you can place the weighing boat provided on the balance and press the Tare button to zero the balance, then place the solid sphere in the weighing boat to determine its mass. 2 your Calculate the density of each (in g/cm2) using the formula (Note: The volume in cm of determined in Expt. B and C.): each solid is Mass Volume 2 Density# Round your answers to the correct number of significant digits and record them with the correct units. In the Data section, make an appropriate data table (an example data table is shown below) to display all your answers and be sure to include the unit of each number in your table. Type of Solid Rectangular Solid Sphere Mass Volume Density 5 26 N

Explanation / Answer

You haven't provided data on the measurements of solids. So I have provided you with the method to solve it.

For Rectangular Solid,

Mass = 30.05 g

Volume = Length x Width x Height

Density = Mass / Volume

Density = 30.05 / (L x B x H) g/m3

For Sphere,

Mass = 35.92 g

Volume = (4/3) x Pi x (radius)3

Density = Mass / Volume

Density = 8.575 / (radius) g/m3
