In this lab, students will determine the density of two unknown metals.
The volume is determined using water displacement and then mass is measured with a digital balance. The data is recorded then plotted. The slope of the trend-line helps determine how many grams there are for every milliliter of volume of the substance. This relationship of unit of mass for every unit of volume is what we call density.
