This example shows three different types of ways a solution stoichiometry question can be asked, using molarity, stoichiometry and dilutions. I walk you through how to solve each part while showing you all the steps of course!

Chemistry Question:
According to the label on a bottle of concentrated hydrochloric acid, the contents are 36.0% HCl by mass and have a density of 1.18g/mL. What is the molarity of concentrated HCl? What volume of it would you need to prepare 283mL of 2.20M HCl? What mass of sodium bicarbonate would be needed to neutralize the spill if a bottle containing 1.75L of concentrated HCl dropped on a lab floor and broke open?
