Concentration It is the term we use to make the relationship between the amount of solute and the amount of solvent in a solution.
Quantities can be given in mass, volume, mol, etc.
no2 = 0.5mol
V = 14L
Each quantity has an index. We use index:
1 = for solute quantities
2 = for solvent quantities
no index = for solution quantities
2g mass of NaCl solute: m1= 2g
number of moles of 0.5mol of water solvent: n2 = 0.5mol
14L solution volume: V = 14L
The concentrations may be:
- Common concentration
- Molar fraction
We will study each one below.
