PERFORMANCE TASK #2DETERMINATION OF DENSITIESDISCUSSION :The density of an object is defined as its mass per unit volume. Mathematically it canbe expressed as:Formula :D= M/VWhere :D= density , M= mass , V= volumeThis usually expressed as grams per millilter (g/ml ) for liquids , grams per cubiccentimeter (g/cm3) for solid , and grams per Liter (g/L) for gases.I.OBJECTIVES :After completing the activity , you should be able to:1. Learn the proper technique in measuring the mass and the volume ;2. Determine the densities of some solids and liquids , and3. Apply the rules of significant figures when reporting the weight,volume and density of each material.II-INSTRUCTION :1.0 DENSITY OF LIQUIDS:1.1 Density of waterTo determine the density of water , first is to get the mass of the waterbased from the given value below by obtaining the difference from themass of empty cylinder and mass of the graduated and water .Assume thatthe volume of water is 40 ml . Compute its density .
