The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium h
7nadin3 [17]

Answer:  

0.022 M

Explanation:

The molarity is the number of mol solute divided by the volume of solution in liters. Since we are told there is only one acidic hydrogen in KHP  the reaction is a 1 to 1 with sodium hydroxide, We then calculate the moles of sodium hydroxide required to react with the  moles of KHP and proceed to calculate the molarity of the NaOH solution:

mol KHP:  0.1082 g  x  1 mol/204.22 g = 0.00053 mol KHP

0.00053 mol KHP x 1 mol Naoh/1 mol KHP = 0.00053 mol NaOH

Molarity of the solution :  0.00053 mol NaOH / 0.02346 L = 0.022 M

note: The volume of sodium hydroxide needed to be converted to liters by definition of molarity.
