How many milliliters of a 0.81 M HCl solution are needed to react completely with 2.2 g of zinc to form zinc(II) chloride?

• Chemistry -

Write the equation and balance it.
Convert 2.2 g Zn to mols. mols = grams/molar mass.
Use the coefficients in the balanced equation to convert mols Zn to mols HCl.
M HCl = mols HCl/L HCl. You know moles and M, solve for L HCl and convert to mL.
