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 measurements using the following formula. % Error = */Standard value - observed mean/ x 100 Standard value Table 1.

a) Analytical balance c) Calibrated measuring plastic cups (8 fl. oz) e) Wood blocks g) small white plastic cups Procedure: The following procedures were used in the volume, mass, and length measurements using the equipment shown above, to generate the theoretical data given in the Tables below. 1. 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 observing 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 quantitative 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. b) Graduated cylinders d) Rulers (inches and centimeters) f) metal rounds 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 measurements using the following formula. % Error = */Standard value – observed mean/ x 100 Standard value Table 1. Volume Measurements Replicate #1 #2 #3 *absolute difference (no negative sign) Volume (ml) 92 88 89 Volume (fl. oz.) 3.0 2.9 3.0 Mean % Error Ratio (ml/ fl. oz) 2. Mass Measurements (procedure) The mass of three metal rounds is measured, one at a time, in grams and oz on analytical balance, and data entered in the appropriate column in Table 2. First, one of the metal rounds is placed on analytical balance, set on gram (g) unit, and data observed and recorded to the nearest hundredths of a gram on the Data Table 2, first row, second column. Then, the unit on the balance is switched to ounce (oz) scale and the mass of the same metal round is measured in oz and the data is entered first row, third column. The same procedure of measuring the mass in gram and oz continues for the second and third metal rounds, and data entered in ●●●
