Calculated Molarity of KMno4- Calculations are preferred in 4 significant figures
A1 =0.0195 M
A2= 0.0193 M
A3= 0.0148 M
A =Average = Sum/3 = 0.0179
Standard deviation calculation:
= Sqr root[{ (sqr (A-A1) + Sqr (A-A2) +sqr (A-A3) } / 3 ]
= 0.0022.
The concentration of solutes is of great importance in the study of chemical reactions because it determines the frequency with which molecules in solution collide, indirectly determining reaction rates and equilibrium conditions. See chemical equilibrium. Concentration can be expressed in many ways. Solution concentration is defined as the amount of solute present in a given volume of solution. Divide the mass of the solute by the total volume of the solution. Write down the formula C = m/V. where m is the mass of the solute and V is the total volume of the solution.
