Calculate the molarity of the sodium hydroxide.

24.46 mL of the sodium hydroxide solution was required to react with 0.1082 g KHP.It would be great if I could get some help!-I think youre supposed to use the equation formula Molarity = moles of substance/ volume in liters, or M=m/v.......
The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium hydrogen phthalate (abbreviated as KHP). KHP is an acid with one acidic hydrogen and a molar mass of 204.22 g/mol. In the titration, 24.46 mL of the sodium hydroxide solution was required to react with 0.1082 g KHP.

It would be great if I could get some help!

I think you're supposed to use the equation formula Molarity = moles of substance/ volume in liters, or M=m/v. Before plugging your given values into the equation, you must change your units, so convert 24.46mL to L and convert 0.1082gKHP to moles using the molar mass.

Try doing it yourself first, but if you want to check your answers:

Volume= 0.02446L
moles= 0.1082g KHP x (1 mol/204.22g) = 0.1082/204.22= 5.3 x 10^-4 mol KHP

NOW you can plug the new values into the equation M= mol/vol

M= (5.3 x 10^-4 mol)/(0.02446L)= 0.02166 M, then round if needed for sigfigs
