On day in hallowed halls of the Wood, a piece of evidence to a crime appeared. It was a
gigantic pellet of sodium hydroxide. The whole solution to the crime depended upon the
mass of the pellet. Sadly the fairy balance beam wasn’t working , but the fairy Godmother
remembered her chemistry and knew she could find the mass of the pellet by conducting
various laboratory experiments. She found that when she added 18356 mL of 0.100 mol
/L HCl to a solution made by dissolving the pellet in a sample of water, the indicator
phenolpthalein changed from pink to clear. What was the mass of the pellet?
