Volume

made by a company manufacturing them will be assessed. This will be done by taking different volumes of water using a 10 mL graduated pipet, a 50 mL graduated buret, a 10 mL graduated cylinder, and a 50 mL graduated cylinder. After weighing each volume, we used the density of water at our room temperature to calculate the volume of each water samples. Then we compared that calculated volume (actual volume) to the one initially took; we used that result to assess the accuracy of our glassware by doing

found with the formula D=m/v. Which is defined as mass divided by volume to find the density. Procedure First, each metal’s description and weight was recorded. Additionally, the weights of each cylinder used was recorded. Next, a graduated cylinder was filled with 20mL of water and unknown metal II was fully submerged in the water 3 times. Each time, the volumes were recorded and the difference between the final volume and initial volume was calculated. This test was repeated for unknown metal IV.

the amount of material present. The formula for density is density=mass/volume(d=m/v). Introduction Density is a measurement of the amount of mass that have a specific volume. Density is used for identifying substances. Density is reported as g/ml or g/cm³. This lab will focus on measurements. Mass and volume are physical properties that can be easily measured. In the lab, the mass was measured in grams and the volume was measured in ml. Limitations on results The percent error when

determine whether boiling point, density, mass, and volume are intensive or extensive properties two experiments will be conducted. One experiment will be dedicated to identify if boiling point is an intensive or extensive property by boiling water at different quantities. The other experiment will identify if density and mass are intensive or extensive properties by utilizing a grape. The experiment will consist of measuring the mass and volume of a grape to determine the density. Both of these experiments

mL is the same volume as one cubic centimeter (1 ml = 1 cm3). Materials: none Pictures will be provided of the experiment. Materials used in obtaining the pictures are a bag of regular (NOT peanut) M&Ms (about 8 oz), plastic vernier caliper, and 100 ml plastic graduated cylinder. Procedure: Start with a clean and dry 100 ml plastic graduated cylinder. Add M&Ms until the graduated cylinder is about 3/4 full. Gently tap the graduated cylinder to "settle" the M&Ms. Read the volume of M&Ms in cm3

the amount of mass inside a specific volume of the material. The density does not change with the size or shape of the object, so it can be determined using any size sample of the material by dividing its mass by its volume. The mass of a material can be found easily using an electronic balance; however, the volume of the material had to be found in several different ways. The first method was used only for the metal, and it involved calculating the volume geometrically by taking measurements

The volume was determined by subtracting 20 mL from 25 mL. The volume equaled 5 mL for the unknown substance. Next, we filled the water to 20 mL in the graduated cylinder. Then, placed aluminum in the water, the water increased and measured 25 mL. The volume was determined by subtracting 20 mL from 25 mL. The volume equaled 5 mL for aluminum. After that, we added water to the graduated cylinder to 20 mL. Then, placed the zinc in the water, the water increased and measured 22.5 mL. The volume was

Boyle's Law is where at constant temperature, the volume of a gas is inversely proportional to its pressure; it was named after the man who discovered it, Robert Boyle (West, The Original Presentation of Boyle's Law). In the past, he tested his theory by using a siphon to trap air and see the affects that would occur as he added pressure to the air in his siphon (Fowler, Boyle's Law and the Law of Atmospheres). More recent tests have been done by attaching a syringe to a pressure detector. After

Hypothesis The objective of the density determination lab is to determine/compare the average density of pre-1982 and post-1982 pennies. This can be achieved by finding the mass to volume ratio then averaging the results. The purpose of this lab is to find out if the difference in composition of the pre and post pennies will affect their densities. Pennies made before 1982 where majority copper but pennies minted after 1982 are made with mostly zinc. With this background knowledge, we expect the
