Concentration Calculations

In order to correctly calculate differing solution quantities, it is helpful, if not essential, to become familiar with dimensional analysis and with the inter-conversion of solution amounts.

Dimensional Analysis

The practice of dimensional analysis involves the use of units, and the carrying along of those units, during calculations. It is not too difficult to calculate a number from a word problem, but to end up with the correct units is another issue.

Including the correct units with a calculated result is important for two reasons

  • they lend validity to your answer
  • they often tell you whether or not you have correctly performed the calculations
