C6H8O7 (aq) + 3 NaHCO3 (aq) → 3 CO2 (g) + 3 H2O (l) + Na3C6H5O7 (aq) Based on the above equation, how do I use the amount/volume of CO2 produced to determine the percent composition of citric acid and sodium bicarbonate in Alka Seltzer? Here are the instructions: C6H8O7 (aq) + 3 NaHCO3 (aq) → 3 CO2 (g) + 3 H2O (l) + Na3C6H5O7 (aq) Use the Ideal Gas Law to determine the amount of collected CO2 Use that quantity to determine the percent composition of citric acid and the percent composition of sodium bicarbonate in Alka Seltzer. They do not need to add up to 100% because there are other ingredients in Alka Seltzer.

Definition Definition Any of various laws that describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. At a constant temperature, the pressure of a particular amount of gas is inversely proportional with its volume (Boyle's Law) In a closed system with constant pressure, the volume of an ideal gas is in direct relation with its temperature (Charles's Law) At a constant volume, the pressure of a gas is in direct relation to its temperature (Gay-Lussac's Law) If the volume of all gases are equal and under the a similar temperature and pressure, then they contain an equal number of molecules (Avogadro's Law) The state of a particular amount of gas can be determined by its pressure, volume and temperature (Ideal Gas law)
