When an antacid tablet dissolves in water, the fizz is due to a reaction between sodium hydrogen carbonate (sodium bicarbonate, NaHCO3) and citric acid (H3C6H5O7). 3 NaHCO3(aq) + H3C6H5O7(aq) 3 CO2(g) + 3 H2O(l) + Na3C6H5O7(aq)
How many moles of Na3C6H5O7 can be produced if one tablet containing 0.0361 mol of NaHCO3 is dissolved?
