GCHEM I LAB DENSITY CONCEPT PROBLEMS DENSITY SOLID or LIQUID (grams/cm 3 ) = Mass (grams)/ Volume (cm 3 ) DENSITY SOLUTION (grams/cm 3 ) = [Mass Solute + Solvent] (grams)/Volume Solvent (cm 3 ) DENSITY GEOMETRIC SOLID (grams/cm 3 ) = Mass (grams)/Volume Geometric Solid (cm 3 ) Ex: Formula Volume Cylinder = (π) * (r 2 ) * (length) What is length of cylinder ? mass/D = Calculated Volume Cylinder mass/D = (π) * (r 2 ) * (length) Solve equation for (length) Volume Liquid: 1 milliliter (ml) of water = 1 cm 3 of water at 4 o C 1) A gold ring was weighted on a centi-gram balance and the mass was 24.95 grams. The volume of the ring was determined to be 1.330 cm 3 . What is the density of gold (grams/cm 3 ) ? 2) Bromine is a liquid at room temperature and has a density of 3.824 grams/ml at 25.0 o C. What volume (mls) will 50.0 grams of bromine occupy ? 3) If 75.6 mls of hydrochloric acid (HCl) solution has a density of 1.275 grams/ml. what is the mass (grams) solution ? 4)
