Purpose The purpose of the laboratory experiment was to first confirm that the density of water is around 1.00g/mL. Afterwards, the densities of an unknown solid and an unknown liquid were determined to establish the identities of the two unknowns from a table. Data Water: Mass of 25mL Graduated Cylinder (g) 70.492 Mass of 25mL Graduated Cylinder and Water (g) 84.333 Mass of Water (g) 13.841 Volume of Water (mL) 14 Unknown Liquid N: Trial 1 Trial 2 Trial 3 Mass of beaker (g) 29.345 29.485 29.603 Mass of beaker and unknown 40.191 40.293 40.147
