Determine the volume of a 0.550M of kmno4 solution required to completely react with 2.70 of zn
2.70 WHAT of Zn. grams?
Write and balance the equation.
moles Zn = grams/molar mass
Using the coefficients in the balanced equation, convert moles Zn to moles KMnO4.
Then M KMnO4 = moles/L
You know M and moles, solve for L
