Sodium carbonate (kc = 3.67 *10^-3) is a weak base that can react with two moles of water according to the following equilibrium:

Na2Co3 (aq) + 2 H2O yields H2CO3 + 2 NaOH

if 8.14 mMol of sodium carbonate is dissolved in 100ml of water and allowed to reach equilibrium, what will the concentration of its conjugate acid (H2CO3) be?
