Concentration

• Concentration = mol / dm^3
• Percentage by mass = g solute / g solution x 100% (element/Mr of compound)
• Solution= solvent+solute
• Dilute= lower concentration of solute in a certain volume of solution.
• Concentrated= higher concentration of solute in a certain volume of solution.
• Mass= volume x concentration
• Volume= mass/Mr (x24)
• Mass= concentration x volume (or) Moles= concentration x volume
• Percentage by mass= mass of solute/mass of solution x100%
