Chemists use both very large numbers such as Avogadro's number and very small numbers for example when working with nanoparticles on a regular basis. Using standard form is a very convenient way of dealing with these numbers.After working through this topic you will be able to:

  • write and manipultate numbers in standard form;
  • appreciate some of the difficulties learner face when working in standard form including working with logarithims and the use of calculators; and
  • use stragegies to help learners improve their confidence when they comes across standard form in a chemical context.
