Concentrations of solutions

• Equation for concentration of a solution in terms of moles:

  Concentration ( mol/dm^3) = number of moles / volume ( dm^3 )
• When calculating concentrations of solutions, we calculate using decimeters and give our answer in centimeters
• Equation for concentration in terms of grams:

  Concentration ( g/dm^3 ) = mass ( g ) / volume ( dm^3 )
• 1 decimeter = 1000 centimeters
