Measurement Practice
8/27/13
Purpose: The purpose of this lab is to become familiar with the measuring equipment in the lab, figuring out what piece of equipment is best for measuring and to become familiar with finding density, mass, volume and area. Conclusion: My conclusion of the data is that beakers give you a very poor measurement and should mainly be used for pouring. Burets, pipets, and graduated cylinders should be used for more tedious measurements. Future Actions: The teacher should help the students more. This is most likely the first lab of some students’ college career and would benefit from that. Equipment: This lab requires: a 50mL, 150mL, 250mL beakers, 50mL, 125mL Erlenmeyer flasks, 10mL, 25mL, 50mL, 100mL graduated cylinders, glasses, an apron, 10mL volumetric pipet, 10mL pipet pump, 50mL buret, top loading electric balances, ring stand, buret clamp, and an alcohol thermometer.
Procedure:
Part IA:
Secure a 50mL buret using a ring stand and a buret clamp. Add distilled water until the buret reads “0.00mL”. Drain half of the water into a pre-weighed 50mL beaker. Record the amount of water drained from the buret. Find the mass of the water in the beaker. Record the temperature. Calculate the volume of water. Repeat the procedure, average results, and determine the significant figures.
Part IB:
Using the 10.00mL volumetric pipet, take 10.00mL of water from the 150mL beaker and drain the 10.00mL of water into a pre-weighed 50mL beaker. Calculate the volume of the water in the pipet. Repeat, average results and determine the number of significant figures.
Part IC:
Using your 10.00mL pipet, add 10.00mL of distilled water to a 50mL beaker. Record the volume of water in the beaker. Repeat, average results, and determine the number of significant figures. Repeat with a 150mL beaker and a 125mL Erlenmeyer flask.
Part ID:
With a 10.00mL volumetric pipet, take exactly 10.00mL of distilled water from a 50mL beaker and drain the water into a 25mL graduated cylinder.…
