Density determination - Study guides, Class notes & Summaries

Experiment #: 2 Title: Density Determination Purpose: The purpose of this experiment is to learn how to calculate the density of both liquids and solids in the chemistry lab by finding the volume and mass of different substances. Procedure: Density Determination of Water: 1) A graduated cylinder is to be filled with water 2) The temperature is taken using a digital thermometer of the water in the graduated cylinder 3) A value is read and recorded in ºC for the temperature of the water ...
