â¼ Part A Constants Periodic Table How many moles of Ba(OH) are present in 105 mL of 0.400 MBa(OH)2? Express your answer with the appropriate units. Learning Goal To calculate the concentration of a solution using acid- base titration data. View Available Hint(s) In an acid-base titration, an acid (or base) of known concentration is added to a base (or acid) of unknown concentration until the number of moles of H and OH are equal, a condition called the equivalence point. Since you know the number of moles of H (or OH that you added, you can determine the number of moles of OH (or H) in the unknown solution. 4.20x102 mol All attempts used; correct answer displayed For example, a solution containing 1 mol of H2 SO4 contains 2 mol of ionizable hydrogen atoms, and would therefore require 2 mol of NaOH for neutralization. Enter your answer using dimensions of amount of substance. Part B How many moles of HNOs are present if 4.20x102 mol of Ba(OH)2 was needed to neutralize the acid solution? Express your answer with the appropriate units. View Available Hint(s) Value Units Submit Show transcribed image text
