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.
