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 0.0141 mol of NaHCO3 is dissolved?
mol
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 0.0141 mol of NaHCO3 is dissolved?
mol

Answer:
9.6 mol
Explanation:
Start by writing out the balanced equation of the reaction.
2 +
⇒ 2
Here you will see 2 mol of hydrogen for every 1 mol of oxygen. Using this ratio, you can assume the amount of hydrogen will always be double that of oxygen. In this case, 4.8 * 2 = 9.6
