-LSB- link -RSB- shows the densities of some common substances . While there are many ways to determine the density of an object , perhaps the most straightforward method involves separately finding the mass and volume of the object , and then dividing the mass of the sample by its volume . In the following example , the mass is found directly by weighing , but the volume is found indirectly through length measurements . Measurements provide quantitative information that is critical in studying and practicing chemistry . Each measurement has an amount , a unit for comparison , and an uncertainty .
