concentrations of solutions

• What does concentration tell us?

  Mass of a solute in a given volume
• What is a solute?

  A chemical dissolved in a solvent
• What is often used as a solvent in chemistry?

  Water
• What is the unit of concentration for this definition?

  G per decim cubed
• How is the concentration calculated?

  Mass in grams divided by volume in decim cubed
• How does increasing the mass of solute affect concentration?

  • Increases concentration if volume remains the same
• How does increasing the volume of the solution affect concentration?

  • Decreases concentration if mass remains the same
• What additional resources are available for concentration practice?
