Note: I used 3g of Alka Seltzer, Initial Mass was(Vinegar+water+alka selt) 118.011g, Final Mass is 117.164g, Mass of Co2 evolved was 0.847g, moles of CO2 evolved was 0.01925g/moles
Thank you for the opportunity to help you with your question!
Since the mole ratio is the same for
NaHCO3 and the CO2 produced
So the number of moles of CO2 produced is the same as number of moles of NaHCO3
Hence the number of moles of Alka Seltzer is 0.01925 moles
