The active ingredients in a particular antacid tablet are aluminum hydroxide Al(OH)3, magnesium hydroxide Mg(OH)2 and an inert "binder". A 500 mg sample of the active ingredients was dissolved in 50.0mL of 0.500 M HCl. The resulting solution, which was still acidic required 30.9 mL of 0.255M NaOH for neutralization. (a) Calculate the number of OH ion moles in the antacid tablet. (b) If the antacid tablet contains 5.0% (mass) of the inert "binder" , how many milligrams of aluminum...
