Mineral Density IntroductionThere are many types of minerals in the world. A mineral is a substance that contains only one type of molecule (PbS or NaCl). Minerals naturally occur as homogeneous solids that have a defined chemical composition and a distinctive internal crystalline structure. To calculate density I will use the formulas: Density = Mass / Volume This will give the answer in grams per cubic centimeters (g/cm3) To calculate density you need to know: · Mass (measured in grams · Volume (measured in cm3) My goal is calculate the density of some common minerals. mineral will always have the same density no matter how large or small The apparatus I have chosen the following apparatus because I believe it will produce the most accurate and correct results. These are:· Minerals· A Calculator · An electronic scale · Water · A displacement can · A thread · A glass The method The first thing to do is to create a table on an A4 sheet of paper to record your results. This should include a column for the mass, the volume (within this the four columns three for the three experiments and one for the averages) and the density. Then collect the apparatus. See diagram of the apparatus on the next page , Basalt) or numbered, this is to ensure that they do not get confused. Select a mineral and weigh it using the electronic scale; make sure the electronic scale is zeroed before placing the mineral. This is to make the investigation fair and accurate. Then record the weight (mass) in the table created earlier. Carefully tie the thread around the ore so that the ore can be carefully placed in the moving container. This will make the investigation more correct and accurate. Fill the moving container so that the water flows out
