Iron reacts with HCl solution to give H2 gas and Fe2+ ions. Suppose that 6.5 g of iron are to be dissolved in 1.4 M HCl. What is the minimum volume (in mL) of the acid solution required to react with all of the iron?
Here is a worked example of a stoichiometry problem. After find the number of moles HCl, use M = moles/L to solve for L and convert to mL.
