Aluminum hydroxide reacts with hydrochloric acid in a 1 to 3 mole ratio, producing aluminum chloride and water. The key is to first convert the volume of the solution into liters to work with molarity. Molarity gives moles per liter, so multiplying it by the volume in liters gives the actual number of moles of aluminum hydroxide available. Using the mole ratio from the balanced equation allows calculation of the moles of water produced. Finally, multiplying the moles of water by its molar mass (18.015 g\/mol) gives the mass in grams. Each step applies basic chemistry principles of unit conversion and mole relationships.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-273.jpeg\" alt=\"\" class=\"wp-image-28916\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-273.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-273-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-273-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Aluminum hydroxide reacts with hydrochloric acid to produce water and aluminum chloride: Al(OH)3(aq) + 3HCl(aq) \u00e2\u2020\u2019 3H2O(l) + AlCl3(aq) Determine the grams of water formed by the reaction of 205 mL of 0.669 M aluminum hydroxide solution.
