LESSON: 25 Solution Stoichiometry
Example: 200mL of .362M Iron(II) Chloride reacts with excess copper. How many grams of Iron are produced?
· Balanced Equation: FeCl2 + Cu ®CuCl2 + Fe
0.362 mol x .200L x 1 x 55.8g = 4.04 g
L 1 1 mol
· How many mole of Copper(II) chloride are produced?
0.362 mol x 0.200 x 1 = 0.0724 mol
L 1
· Determine [CuCl2]
0.0724 mol x 1 = 0.362 M
0.200L
Example: A 0.666 M solution of Ba(OH)2 reacts with 32mL of 1.25M HCl. What volume of Ba(OH)2 is required for a complete reaction?
· Balanced Equation: 2HCl + Ba(OH)2 ® BaCl2 + 2HOH
· 1.25 mol x 0.032L x 1 = 0.020 mol
L 2
1 L x 0.020 mol = 0.030 L
0.666 mol
