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  0.02006 moles

Please let me know if you need any clarification. I'm always happy to answer your questions.

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
