how many milliliters of 0.125 M H2SO4 are needed to neutralize 0.200 g of NaOH?

How many grams of CO can react with .150 kg of Fe2O3?

2NaOH + H2SO4 ==> Na2SO4 + 2H2O
mols NaOH = g/molar mass = 0.200/40 = ?
mols H2SO4 = 1/2 that. Look at the coefficients to know that.
M H2SO4 = mols H2SO4/L H2SO4. You know M and mols, solve for L and convert to mL.
