With following equations density was obtained. Mass of substance / Volume of substance = Density of substance Before acquiring unknown solids and liquids, density of water was founded to see whether the equation works. Three experimental trials were performed and in table 1.1 the data and calculation is placed. Table 1.1 : Density of Water Trial # Mass of graduated cylinder (g) Mass of graduated cylinder +10mL of distilled water(g) Mass of water(g) Volume of water(mL) Density of Water(g/mL) 1 68.375 78.04 9.665 10 .9665 2 68.375 78.34 9.965 10 .9965 3 68.375 78.335 9.963 10 .9963 Calculation (78.04g – 68.375g)/10mL = .9665 g/mL (78.34g – 68.375g)/10mL = .9965 g/mL (78.335g – 68.375g)/10mL = .9963 g/mL The average of these three results ( .9665g/mL + .9965g/mL + .9963g/mL)/3 = .9863g/mL . 997 is considered to be the standardized density of water. In order to check the precision of data relative average deviation is used. .9665g/mL - .9863 g/mL + .9965 g/mL - .9863 g/mL + .9963 - .9863 g/mL
