Using concentration of solutions

• Concentration


  The mass of a solute in a given volume of solution
• Concentration in moles per decimeter cubed

  The number of moles of solute divided by the volume in decimeters cubed
• Calculating concentration in moles per decimeter cubed

  Number of moles / Volume in decimeters cubed
• Calculating number of moles

  Concentration x Volume
• Calculating mass of solute

  Number of moles x Relative formula mass
• Calculating concentration of a solution


  1. Write C=N/V equations

  2. Substitute given values

  3. Calculate number of moles

  4. Use mole ratio to find other moles

  5. Divide moles by volume to get concentration
• Concentration


  Moles per unit volume
• Moles


  Amount of substance
• Moles of A = Moles of B in a reaction
• Concentration = Moles / Volume
