Leader: Grady Worksheet 10 Course: Chem 177 Supplemental Instruction Instructor: Kingston Iowa State University Date: 9/28/15 The average concentration of bromide ion in seawater is 65 mg of bromide ion per kg of seawater. What is the molarity of the bromide ion if the density of the seawater is 1.025 g/mL? By titration, 15.0 mL of 0.1008 M sodium hydroxide is needed to neutralize a 0.2053 g sample of an organic acid, what is the molar mass of the acid if it is monoprotic? An elemental analysis of the acid indicates that it is composed of 5.89% H, 70.6% C, and 23.5% O. What is its molecular formula? What volume of .128 M HCl solution is needed to neutralize 2.87g of Mg(OH)2? If 50.10 mL of .135 M HCl solution is needed to neutralize a solution of KOH, how many grams of KOH must be present?
