- A solvent dissolves in a solvent to give a solution
Quantities in Solution
You need to think about two thigs when you deal with a solution
- What amount of solute is dissolved?
- How much solution is there?
These two factors combine to make up the concentration
Units for volume
- The volume of a solution is usually given in cm3 or dm3
- cm3/1000 = dm3
- dm3 x 1000 = cm3
The concentration is calculated by;
Concentration = Number of moles of solute/Volume of solution
Diluting with Water
Dilution Factor = Final Volume/Starting Volume
Final Concentration = Starting Concentration/Dilution Factor
Starting Concentration = Final Concentration x Dilution Factor
'1 mole of any gas occupies the same volume at the same temperature and pressure'
Volume of Gas = Moles x 24
This is not true for liquids or solids
