A lead-acid battery uses a redox reaction in which lead(0) and lead(IV) are both converted to lead(II). This reaction is facilitated by the presence of sulfuric acid, H2SO4, as shown by the reaction:
Pb+PbO2+2H2SO4 -----> 2PbSO4 + 2H2O
Suppose that a fully charged lead-acid battery contains 1.50L of 5.00M H2SO4. What will be the concentration of H2SO4 in the battery after 2.30A of current is drawn from the battery for 9.50 hours?
Express the molar concentration numerically
