How to Calculate Mixed Solution Concentration

Formula

C_final = (C1 × V1 + C2 × V2) / (V1 + V2)

Based on conservation of moles: total moles = sum of moles from each solution.

Example Calculation

Mix 100 mL of 2 M HCl with 200 mL of 0.5 M HCl.

  1. 01Moles from solution 1 = 2 × 100 = 200 (in mL·M units)
  2. 02Moles from solution 2 = 0.5 × 200 = 100
  3. 03Total = 300, Volume = 300 mL
  4. 04C_final = 300 / 300 = 1 M
