Q# Question Text 4) Data Entry - No Scoring. When you used the volumetric pipet to determine the density of water, what was the volume of water in milliliters delivered by your pipet for a single trial? Report your value to 4 significant figures. Volume (mL) = Your Answer: 10 No Points Possible 5) Data Entry - No Scoring. For each of your three acceptable trials, what was the measured mass in grams of water delivered by your 10.00 mL pipet? Report your results to 4 significant figures, e.g 9.988 or 1.008. Your Answer: 10.10 No Points Possible Your Answer: 9.9230 No Points Possible Your Answer: 9.9650 No Points Possible 6) Scoring Scheme: 3-3-2-1. For each of your three acceptable trials, what was the density of water that you determined with your 10.00 mL pipet? Report your results to 4 significant figures, e.g. 0.9988 or 1.008 Your Answer: 1.01 You Scored 3 points out of 3 Possible Your Answer: 0.9923 No Points Possible Your Answer: 0.9965 No Points Possible 7) Scoring Scheme: 3-3-2-1. Using the data for your three trials, what is the average value of the density of water that you obtained using your 10.00 mL pipet? Report your results to 4 significant figures, e.g. 0.9984 or 1.008 d average (g/mL) = Your Answer: 0.9997 You Scored 3 points out of 3 Possible 8) Scoring Scheme: 3-3-2-1. Using the data for your three trials, what is the standard deviation of your data? Report your result to two significant figures, e.g 0.00032 Standard Deviation (g/mL) = Your Answer: 0.0090 You Scored 3 points out of 3 Possible 9) Scoring Scheme: 3-3-2-1. Using the data for your three trials, what is the 90% confidence limit of your data? Report your result to two significant figures, e.g 0.0032

Confidence limit (g/mL) = Your Answer: 0.0150 You Scored 3 points out of 3 Possible 10) Data Entry - No Scoring. What was the temperature of the room and the temperature of the water, to the closest degree Celsius, when you made your measurements for this laboratory? Temperature ( o C) = Your Answer: 19 No Points Possible 11) Data Entry - No Scoring. Referring to Table I in your laboratory manual for this experiment, what is the accepted value for the volume of 1 gram of water at the temperature of the room you reported in the last question? Report 5 significant figures here. Volume (mL) = Your Answer: 1.0026 No Points Possible 12) Scoring Scheme: 3-3-2-1. Using the accepted value for the volume of 1 gram of water at the temperature of the room that you reported above, what is the accepted value for the density of water? Report your result to 4 significant figures, e.g. 0.9997. Density (g/mL) = Your Answer: 0.9974 You Scored 3 points out of 3 Possible 13) Scoring Scheme: 3-2-2-1. Using the value for the average density of water that you determined using your 10.00 mL pipet and the
