The carbon dioxide will be generated by reacting solid sodium bicarbonate (NaHCO3) with a solution of acetic acid (CH3COOH) as follows:
NaHCO3(s) + CH3COOH(aq) ? H2CO3(aq) + CH3COO-(aq) + Na+(aq)
H2CO3(aq) ? H2O(l) + CO2(g)
To get a better value for the volume, you fill the bag with water, then measure the volume of the water to be 513.1 mL. Now you measure room temperature to be 20 °C and the barometer on the wall gives a reading of 764 torr for the atmospheric pressure. Using the ideal gas law, calculate the number of moles of CO2 that will be required to fill the bag at this temperature and pressure.
My answer (which is correct) = 0.0215 mol
Now inspect the reactions above generating CO2 and calculate the molar quantity of NaHCO3 and CH3COOH needed.
Quantity of NaHCO3:
Quantity of CH3COOH:
What mass of NaHCO3 will be needed?
