The metric system prefixes
The Metric System - Prefixes

  • micro = µ = one-millionth = 10-6

  • milli = m = one-thousandth = 10-3

  • centi = c = one-hundredth = 10-2

  • deci = d = one-tenth = 10-1

  • deka = dk = ten times = 101

  • hecto = h = hundred times = 102

  • kilo = k = thousand times = 103

  • mega = M = million times = 106

The metric system length
The Metric System - Length

  • 1 micrometer (µm) = 0.000001 meter

  • 1 millimeter (mm) = 0.001 meter

  • 1 centimeter (cm) = 0.01 meter

  • 1 decimeter (dm) = 0.1 meter

  • 1 dekameter (dkm) = 10 meters

  • 1 centigram (cg) = 0.01 gram

  • 1 decigram (dg) = 0.1 gram

  • 1 dekagram (dkg) = 10 grams

  • 1 hectogram (hg) = 100 grams

  • 1 kilogram (kg) = 1000 grams


The metric system volume
The Metric System - Volume

  • 1 microliter (µL) = 0.000001 liter

Lab procedures
Lab Procedures

  • Recording Data/Lab Notebooks

    • Ink

    • Never rip out pages

    • Never erase data; cross out mistakes

    • Record all information, no matter how trivial

    • Be specific

    • Check all calculations

    • And, obviously, BE NEAT


Lab procedures1
Lab Procedures

  • Bunsen burners


Lab procedures2
Lab Procedures

  • Glass Tubing

    • Cutting

    • Fire Polishing

    • Bending

    • Inserting into stoppers


Lab procedures3
Lab Procedures

  • Transfer of Liquids

    • Correct handling of glass stoppers

    • Pouring liquids from beakers


Lab procedures4
Lab Procedures

  • Loosening stuck stopcocks and stoppers


Lab procedures5
Lab Procedures

  • Weighing/Balances

    • Most important tool in a chemistry lab

    • Used to determine the mass of an object

    • Triple-beam balance

    • Analytical balance


Lab procedures6

Precision

Reproducibility

Check by repeated measurements

Poor precision results from poor techniques

Accuracy

Correctness

Check by using a different method

Poor accuracy results from procedural or equipment flaws
