Volume Three

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

Volume Measurements: The volume of a small test tube and a thin-stemmed pipet were determined in this section of the lab. Water was poured into a small test tube until the water reached the very top edge of the test tube. The test tube was then emptied into a plastic 25 mL graduated cylinder and volume was measured and recorded into data table 3. A think-stemmed pipet was completely filled with water

Laboratory Techniques and Measurements Choose any three objects that are shorter than the metric ruler to measure, such as a CD, Key, spoon etc. OBJECT | LENGTH (cm) | LENGHTH (mm) | ruler | 30.5 cm | 305 mm | thermometer | 15.1 cm | 151 mm | pencil | 16.7 cm | 167 mm | Warm Temperature Measurements * Fill a 100 a 100mL beaker with 50mL of hot water. Get the water as hot as possible. * Use thermometer to measure the temperature of the water in the beaker using Celsius unit

the force exerted on an object by physical contact, was used to apply force into the pressure sensor. A pressure sensor measures the amount of force can object has and this will tell us how the pressure is affecting the number of particles. Also the volume, of the pressure

dimensions of the object and water displacement. These are two ways of finding the volume of an object, and they were chosen since the density of an object may be found using its mass and its volume. The experiment yielded two different density values, however when error analysis was conducted, the water displacement method was proven to be more accurate. INTRODUCTION

The objective of this experiment is to determine the correlation between a solution’s salt concentration and its density. Also, it was to determine what equipment would be best to use to measure volume precisely and accurately. Densities of a series of known salt solutions were trialed three times and then averaged. By following the procedures, the unknown salt solution was determined and graphed to calculate the percent salt to the sample. Introduction In chemistry there are often times an unknown

equal to mass divided by volume and that the volume of a cylinder is equal to (πr2h)/4. Therefore, the density formula of a cylinder, p=(4m)/(πd2l), was used to calculate the density of the solid, which was computed to be 7.16 g/cm3. After determining this value and doing further research, the group concluded the metal’s unknown composition to be chromium, which has a density of 7.19 g/cm3. The measurements related to the density of the cylinder required obtaining three types of average measurements

surface area and wasted space to that of the cylinder containers currently used. Another container that could be used instead of a cylinder is a rectangular prism as shown below. This investigation will use measurement to calculate the surface area and volume of 3D objects, including a sphere and cylinder. The maths that was used to calculate the results
