Unformatted text preview: red values = calculated value with units Percent error is a common method used to express the accuracy of a measurement. Percent error is calculated using the formula % Error = x 100 = (0.997 g/mL –       g/mL) 0.997 g/mL = answer % Density – Trial 2 (g/mL) Average Density (g/mL) Percent Error (true value -calculated value) true value Table 2. Insert title for Table 2 Density – Trial 1 (g/mL)                         Answer the following questions in present tense using paragraph organization. Does the density of water that you determined experimentally agree with literature value for the density? If there are any discrepancies, how can you account for them? The focus of the second part of the experiment is the effect of temperature on the density of water. For this analysis, a sample of water was heated and the volume of the water at various temperatures was recorded. These data are used to calculate the density of water at various temperatures. These values are recorded in Table 3. Table 3. Title for table 3 Corrected Volume (mL) Temperature (°C) Density (g/mL) Corrected Volume (mL) Temperature (°C) Density (g/mL) Trial 1 Trial 1 Trial 1 Trial 2 Trial 2 Trial 2    ...
