1.45 M is concentration of the final solution.
volume, KMnO4 solution =37.2 mL
Molarity, KMnO4 solution =1.69 M
volume, KMnO4 solution =16.10 mL
Molarity, KMnO4 solution =0.891 M
The millimoles, KMnO4 solution = M x V (in mL)=1.69 x 37.2 =62.868 mmol
The millimoles, KMnO4 solution = M x V (in mL)=0.891 x 16.10 =14.3451 mmol
Total millimoles=62.868 +14.3451 =77.2131 mmol
Total volume = 37.2 + 16.10 =53.3 mL
Final concentration=77.2131 mmol/53.3 mL=1.4486 mol/L
Final concentration=1.45 M
In chemistry, concentration is the amount of a substance in a given space. Another definition of concentration is the proportion of the solute to the solvent or whole solution. Typically, mass per unit volume is used to denote concentration. However, the solute concentration can also be expressed in volumetric or molecular units. Instead of using volume, concentration can be stated as a mass per unit. Despite being frequently used to chemical solutions, concentration may be calculated for any combination.
