## Question:

How can you calculate the average number of moles of OH- used in titrations and the average number of moles of {eq}HC_4H_4O_6^- {/eq} in a 25.0-mL sample of a solution containing bitartrate, which is a weak acid that reacts with sodium hydroxide? The net ionic reaction is: {eq}O{{H}^{-}}(aq)+H{{C}_{4}}{{H}_{4}}{{O}_{6}}^{-}(aq)\to {{H}_{2}}O(l)+{{C}_{4}}{{H}_{4}}{{O}_{6}}^{2-}(aq) {/eq}. Additionally, how can you calculate the average molarity of the {eq}HC_4H_4O_6^- {/eq} in the solution and the average mass of {eq}KHC_4H_4O_6 {/eq} dissolved in 100 mL of water?

## Average Molarity:

Average molarity refers to the average concentration of a solution over a given period of time or in a specific sample. It is calculated by taking the total amount of solute present in the solution and dividing it by the total volume of the solution. Average molarity is commonly used in chemistry to describe the concentration of solutions that may change over time or that are not completely homogeneous throughout.
