H3C6H5O7(aq) + 3 NaHCO3(aq) �¨ Na3C6H5O7(aq) + 3 H2O(l) + 3 CO2(g) How do you go about calculating theoretical yield of carbon dioxide from 1.00g of sodium bicarbonate andthe percentage yield
I what to calculate them both, just don't understand how to
Follow my instructions to calculate theoretical yield, then plug the actual yield you have into the second equation I wrote to obtain % yield.
okay thanks. one more question how do you convert moles NaHCO3 to mols CO2
mols NaHCO3 = mols CO2
To calculate the theoretical yield of carbon dioxide (CO2) and the percentage yield, you need to follow these steps:
1. Determine the balanced chemical equation: The given equation is already balanced, so no further adjustments are required.
2. Identify the stoichiometry: From the balanced equation, you can determine the molar ratio between sodium bicarbonate (NaHCO3) and carbon dioxide (CO2). In this equation, the ratio is 3:3, meaning that 3 moles of NaHCO3 will produce 3 moles of CO2.
3. Calculate the moles of sodium bicarbonate: You have 1.00g of sodium bicarbonate, so you need to convert this mass to moles. The molar mass of NaHCO3 is 84.01 g/mol. Therefore, the moles of NaHCO3 can be calculated as:
Moles = Mass / Molar mass
Moles = 1.00g / 84.01 g/mol
4. Determine the moles of carbon dioxide: Since the ratio of moles of NaHCO3 to CO2 is 1:1, the moles of CO2 produced will be the same as the moles of NaHCO3.
5. Convert the moles of carbon dioxide to grams: To get the theoretical yield of CO2, you need to convert the moles of CO2 to grams. The molar mass of CO2 is 44.01 g/mol. Therefore, the mass of CO2 is determined as:
Mass = Moles × Molar mass
6. Calculate the percentage yield: The percentage yield is calculated as the actual yield divided by the theoretical yield, multiplied by 100%. Since the actual yield is not given in the question, we can't determine the percentage yield without that information.
Remember, the percentage yield is determined by the actual amount obtained in the experiment compared to the calculated theoretical yield.
By following these steps, you can calculate the theoretical yield of carbon dioxide from 1.00g of sodium bicarbonate and determine the percentage yield once the actual yield is known.
mols NaHCO3 - grams/molar mass
Use the coefficients to convert moles NaHCO3 to mols CO2.
mols CO2 = mols NaHCO3 x (3 mol CO2/3 mol NaHCO3) = mols NaHCO3 x (3/3) = ?
Convert mols CO2 to grams. g = moles x molar mass. This is the theoretical yield of CO2.
You can't do percent yield unless you have the actual yield in the problem and you just didn't post that part.
%yield = (actual yield in g/theoretical yield)*100 = ?
Or have I misinterpreted the problem? You want to calculate theoretical yield and you have percent yield?
