Moles and concentration

• What is the formula for concentration in mol/dm³?

  Concentration = Number of moles / Volume
• What does the term 'concentration' refer to in chemistry?

  It refers to the amount of solute in a solution
• In what units is concentration measured?

  mol/dm³
• How is concentration calculated using the number of moles and volume?

  Concentration is the number of moles divided by volume
• What does 'n' represent in the concentration formula?

  'n' represents the number of moles
• What does 'V' represent in the concentration formula?

  'V' represents the volume of solution
• What is the relationship between moles and concentration?

  More moles increase concentration in a fixed volume
• If you have 2 moles of solute in 4 dm³ of solution, what is the concentration?

  0.5 mol/dm³
• How does changing the volume of a solution affect its concentration?

  Increasing volume decreases concentration if moles are constant
• What is concentration

  The amount of stuff per unit volume
