Here are the essential concepts you must grasp in order to answer the question correctly.
Saponification Reaction
Saponification is a chemical reaction between a fat or oil and a base, typically sodium hydroxide (NaOH), resulting in the formation of glycerol and soap. In this context, ethyl octanoate, an ester, undergoes hydrolysis in the presence of NaOH to produce octanoic acid and ethanol. Understanding this reaction is crucial for calculating the amount of NaOH needed for complete hydrolysis.

Molarity (M)
Molarity is a measure of concentration defined as the number of moles of solute per liter of solution. In this problem, the NaOH solution has a molarity of 0.315 M, indicating that there are 0.315 moles of NaOH in every liter of solution. This concept is essential for determining how much volume of the NaOH solution is required to react with the given mass of ethyl octanoate.

Stoichiometry
Stoichiometry involves the calculation of reactants and products in chemical reactions based on balanced equations. To find the volume of NaOH needed, one must first determine the moles of ethyl octanoate present and then use the stoichiometric ratios from the saponification reaction to find the corresponding moles of NaOH required. This concept is fundamental for solving the problem accurately.
