1.3.3 Moles and solutions

Note: another unit for concentration g/L

1. Use square brackets to show concentration, eg [HCl] = 2.0 M
2. 1 L = 1 dm³
   1 mL = 1 cm³
   1 L = 1000 mL
3. Must find the number of moles first before doing ratio (similar to the other calculation)

Dilute a solution

• To make a dilution is to make a smaller concentration from a more concentrated solution (stock solution) by adding solvent.
• Serial dilution is to dilute multiple times
