The project will involve determining the roots of a virial equation of state with cubic order dependency on specific volume. This program can be used in the future for helping to….
Determine the mass of sugar added
CHM 117 Experiment 1 Spring 2018
Scientific Measurements Benchwork Instructions
• Procure a wooden block, an Aluminum block and a ruler from the hood.
• Measure the three dimensions (length, width, height) of the two blocks. Record the values for each material.
• Use the analytical balance to determine the mass of each of the solid blocks of material. Record the values for each material.
• Obtain a 10-mL graduated cylinder, a 25-mL graduated cylinder and 50-mL beaker.
• Make sure that both cylinders and the beaker are clean and dry. Use the analytical balance to determine their masses. Record the values for each item.
• Fill the two graduated cylinders and the beaker with water up to three quarters of their capacity. Record the exact volume in each of the containers by reading the respective scale on their sides.
• Use the analytical balance to determine their masses. Record the values for each item.
Combining Measurements to Determine the Density of a Solid
• Fill the 50-mL cylinder to one-quarter of its capacity. Read and Record the exact volume.
• Determine the mass of a 50-mL cylinder and water and record the value.
• Obtain 20 aluminum pellets. Carefully to avoid splashing, pour the pellets into the cylinder containing water.
• Read and record the volume in the cylinder.
• Determine and record the mass of the cylinder containing water and pellets.
Using the Density of a Solid to determine its dimensions.
• Obtain a piece of aluminum foil and measure the width and length.
• Fold the foil into a small piece and use an analytical balance to determine its mass. Record the value.
Measuring the Mass by Two Different Techniques
• Procure a 50-mL beaker. Use the analytical balance to determine its mass. Record the value.
• Tare the balance and add two spoonfuls of sugar (or salt) to the beaker.
• Determine the mass of sugar added. Record the value.
• Remove the beaker from the balance and tare it.
• Place the beaker back on the balance and determine the combine mass of the beaker and the sugar. Record the value.
