weight of Na2CO3=2.028g;mass of CO2=0.810 g
What is the percentage yield from Na2CO3 being added to HCl to form CO2?
List reasons why it may or may not be 100%.
MW Na2CO3 105.9784 g mol−1
MW CO2 44.01 g mol−1
Na2CO3 is 2.028g or 0.0192 mol
CO2 is 0.810 g or 0.0184 mol
only lacking then 0.0192-0.0184 = 7.5x10^-4 mol
not reacting 7.5x10^-4 mol*105.9784 g mol−1=0.079g
yield is around 96%
not 100% surely because the solid passivates with salt clusters
