Purpose: To determine the density of objects. Introduction: All matter has mass and volume. Mass and volume are physical properties of matter and may vary with different objects. For example, it is possible for two pieces of metal to be made out of the same material yet for one piece to be bigger than the other. If the first piece of metal is twice as large as the second, then you would expect that this piece is also twice as heavy (or have twice the mass) as the first. If both pieces of metal are made of the same material the ratio of the mass and volume will be the same. We define density () as the ratio of the mass of an object to the volume it occupies. The equation is given by: here the symbol M stands for the mass of the object, and V for the volume. Density has the units of mass divided by volume such as grams per centimeters cube (g/cm3 ) or kilograms per liter (kg/l). Sample Problem #1 A block of wood has a mass of 8 g and occupies a volume of 10 cm3 . What is its density? lab report
