Problem 7 a golden colored cube is handed to you the person wants you to buy it for 100 saying that is a gold nugget you pull out your old geology text and look up gold in the mineral table and read that its density is 193 g cm 3you measure the cube and find that it is 2 cm on each side and weighs 40 g. This density example problem shows how to calculate the density of a material when the mass and volume are known this example problem shows how to find the density of an ideal gas when given the molecular mass pressure and temperature this example problem shows the steps necessary to convert inches to centimeters. Word problem exercises science density problems a few fun density problems for you general questions what is the density of a piece of wood that has a mass of 250 grams and a volume of 294 cm 3 1 if the mass of solution is measured to be 6075 grams what is the density of the solution 7. Where density m mass v volume example problems 1 calculate the density in g ml of 30 ml of solution that weighs 120 grams 2 calculate the density in g ml of 04 l of solution weighing 150 grams. Density is a measure of how much matter is in a space it is expressed in units of mass per volume such as g cm 3 or kg l this is a worked example of how to calculate the density when given the volume and mass of a substance
