**Problem Statement:** Use the References to access important values if needed for this question. A 10.5 g sample of an aqueous solution of hydroiodic acid contains an unknown amount of the acid. If 18.3 mL of 0.582 M barium hydroxide are required to neutralize the hydroiodic acid, what is the percent by mass of hydroiodic acid in the mixture? **Answer format:** [ ] % by mass --- **Explanation:** In this problem, you are tasked with finding the percent by mass of hydroiodic acid in a given aqueous solution. The solution involves a neutralization reaction where 18.3 mL of 0.582 M barium hydroxide (Ba(OH)₂) is used. The percent by mass is a common way of expressing the concentration of a component in a mixture. To solve this problem, you will likely need to use stoichiometry and molarity concepts to determine the mass of hydroiodic acid present in the sample, then calculate its percentage of the total mass of the solution.
