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?
0.102 x (molar mass NaHCO3/molar mass CO2) = ? g NaHCO3.
% mass in sample = (mass NaHCO3/mass sample)*100 = ?
