Answer

• Concentration (molarity) of the solution = 1M
  Explanation:
  C1V1 = C2V2
  C1 = Concentration of the HCl = 3 M
  V1 = Volume of HCl = 50 mL
  C2 = Concentration of the solution = ?
  V2 = Volume of the solution = 50 + 100 = 150 mL
  3 * 50 = C2 * 150
  150 = 150 C2
  C2 = 150 / 150
  C2 = 1 M
  Concentration of the solution is 1 M
