Laboratory Techniques & Measurements
Title: Laboratory Techniques & Measurements
Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume, mass, length, and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions.
Procedure: I used a ruler, thermometer, and scale to take measurements. I used a graduated cylinder, short step pipet, scale, and ruler to determine volume and density. I used a volumetric flask, graduated pipet, pipet bulb, scale, and glass beaker to determine concentrations and densities of various dilutions.
Data Tables:
|Data Table 1: Length |
|CD |12 cm |120 mm |0.12 m |
|Key |5.3 cm |53 mm |0.53 m |
|Spoon |16 cm |160 mm |0.16 m |
|Fork |20.5 cm |205 mm |0.205 m |
|Data Table 2: Temperature |
|Hot from tap |48°C |118.4°F |321°K |
|Boiling |100°C |212°F |373°K |
|Boiling for 5 minutes |100°C |212°F |373°K |
|Cold from tap
