Question

Chemistry help?!?!

I need to write a lab paper and I don't understand this question.


If a typical antacid tablet contains 2.0 g of sodium hydrogen carbonate, how many moles of carbon dioxide should one tablet yield?

Answer 1

Your equation should be: NaHCO3 + H+ -----> H2O + CO2 + Na
(I'm not sure of the source of H+, maybe potassium bitartrate?)
? mol CO2 = 2.0 g NaHCO3 x 1 mole CO2/ 84 g NaHCO3 = 0.024 mole CO2
volume CO2 = 0.024 mole CO2 x 22400 mL CO2/mol Co2 = 533 mL CO2
% yield = 100% x 67.3 mL/533 mL = 12.6% (This ignores the conversion to STP)

Answer 2

You are in the wrong topic. This is math @TuringTest

Answer 3

I don't understand what that means though...

@Saphira_Shapiro It's for my chemistry class though

Answer 4

There is a chemistry/science subject. Go there. This is math

Answer 5

That makes much more sense! Thanks! I just joined this website -.-
