Iron reacts with HCl solution to give H2 gas and Fe2+ ions. Suppose that 5.3 g of iron are to be dissolved in 1.7 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 such as this. After you determine the mole HCl, then M = mole/L. You ave moles and M, solve for L and convert to mL.
