Consider the unbalanced chemical equation: H2SO4 (aq) + Fe(OH)3 (S) → Fe2(SO4)3 (S) + H2O (L)
A volume of 38.0 mL of aqueous H2SO4 solution was required to
react completely with 0.685 g Fe(OH)3 (molar mass = 106.8 g/mol)
to produce Fe2(SO4)3. Calculate the molar concentration of the
H2SO4 solution.
A) 0.253 M
B) 0.344 M
C) 0.214 M
D) 0.301 M
E) 0.175 M
