Determine which reactant is the limiting reactant, if,
Mass of Sodium Bicarbonate= 2.00g
Mass of Citric Acid = 0.76g
Are my calculations right, or is it wrong?
(2.00g of NaHO3)(1mol/84.01g of NaHO3)(1mol of H3C6H5O7/ 3 mol of NaHO3)(192.14g of H3C6H5O7)= 1.52g of citric acid
Therefore, citric acid is limiting reactant since 0.76 g of citric acid is less than the equivalent amount which is 1.52g.

I agree.
Then, if it asks to calculate the theoretical yield of carbon dioxide based on my limiting yield,
(0.76g citric acid)(1 mol/ 192.14g citric acid)(3mol CO2/ 1mol)(44.01g CO2/1 mol)= 0.52g CO2
is that right? And if that is correct can the percent yield be over a 100% cause my percent yield came out to be 127%
* mass of carbon dioxide= 0.66g
my calculations for percent yield:
(0.66g/0.52g)(100)= 127%
(0.76g citric acid)(1 mol/ 192.14g citric acid)(3mol CO2/ 1mol)(44.01g CO2/1 mol)= 0.52g CO2
is that right? And if that is correct can the percent yield be over a 100% cause my percent yield came out to be 127%
* mass of carbon dioxide= 0.66g
my calculations for percent yield:
(0.66g/0.52g)(100)= 127%
