Volume Measurements (procedure) The small white cup is filled to the lid with water. The volume of water in the cup is poured into a 100-mL graduated cylinder and the volume is measured by obscrving the bottom of the meniscus to half a subdivision (0.5ml). The volume in milliliters (ml) is recorded on the Data Table 1, first row, second column. Then the volume of water from the graduated cylinder is quaniftative poured into a calibrated plastic measuring cup with care and volume is measured in fluid ounces (fl.oz.) and recorded in column three, first row on the Data Table 1. Replicate this volume measurement 3 times, for the second and third row. Assignment Based on the theoretical data generated following the procedure outlined above and given in Table 1, determine the volume ratio (last column) by dividing the volume in milliliters (column two) by the volume in fluid ounces (third column). Calculate the mean of the 3 ratios (sum of the ratios, last column, divided by three), which should be near the standard value, which is 29.6 ml/fl.oz. Calculate the percent error of your mcasurements using the following formula. % Error=*/Standard value-observed mean/x 100 Standard value *absolute difference (no negative sign) Table 1. Volume Measurements Replicate Volume (ml) Volume (fl. oz.) Ratio (ml/ fl. oz) 92 #2 88 68 Mean
