Assignment #2 Chemistry 1R03 For all questions, ensure that you report your answers to the correct number of significant figures! 1. How many grams of ammonium bicarbonate are required to make 450.0 mL of 1.55 M concentration? 2. Consider the following reaction: Pb(NO 3 ) 2 (aq) + 2KI (aq) 2KNO 3 (aq) + PbI 2 (s) a. How many mL of 0.400 M KI are required to completely react with 25.0 mL of 0.250 M lead (II) nitrate? b. How many grams of lead (II) iodide will be produced? c. What will be the concentration of potassium nitrate in the resulting solution? 3. A neutralization reaction is one where an acid reacts with a base. When the number of moles of acid and base are stoichiometrically the same, the the acid (or base) has been neutralized. The resulting products of such a reaction are a salt and water. Consider the reaction of hydrobromic acid (HBr) and sodium hydroxide. How many grams of solid sodium hydroxide would need to be added to completely neutralize 35.0 mL of 1.45 M HBr? 4.
