You have 45.6 mL of 10.1 M HBr. You need to use Mg(OH)2 to neutralize it. How many grams of Mg(OH)2 are necessary? Step 1: (a) Write the chemical reaction. (b) Check the subscripts for each new compound. (c) Balance the equation (check the big numbers in front of each compound). Step 2: Determine how many moles of HBr you have. (Hint: M = moles/liter) Step 3: Use the chemical reaction (recipe) to determine how many moles of Mg(OH)2 you need. Step 4: Use the Periodic Table to determine how many grams of Mg(OH)2 you need.
