Determine the volume of a 0.550 M KMnO4 solution required to completely react with 2.80 g of Zn.

  • chemistry - ,

    1. Write the equation and balance it.
    2. Calculate moles Zn. mol =- g/molar mass
    3. Using the coefficients in the balanced equation, convert mols Zn to mols KMnO4.
    4. The M KMnO4 = moles KMnO4/L KMnO4.
    You knolw M and moles, solve for L and convert to mL.
