23.9 cm^3 of barium hydroxide solution required exactly 25.0^3 of 0.0871 mol dm^3 nitric acid for complete neutralization. Calculate the molar concentration of the barium hydroxide solution by carrying out the following steps:

a) Calculate the number of moles of nitric acid used in this titration
b) Calculate the number of moles barium hydroxide in 23.9 cm^3 of solution using the equation to provide a link from a)
c) Now calculate the molar concentration of the barium hydroxide
