a student used a 0.358 g sample of Alka-Seltzer and the mass of CO2 was found to be 0.102 g. Based on this result, answer the following questions:

Determine the mass of NaHCO3 that produced the CO2 in the experiment.

Determine the % mass of NaHCO3 in the sample.



Determine the mass of NaHCO3 in the tablet assuming the mass of the tablet is 3.50 g


How do I go about answering these questions?
