Question

I need help with chemistryCalculate the actual yield of carbon dioxide for Trial 4. Start with the volume of carbon dioxide collected. Convert that volume to units of liters. Then use the following equivalence statement to convert from volume in liters to moles of gas:1 mol CO2=24 L CO2My volume was 340 mL

Answer 1

The experiment involves the following reaction:

`\begin{gathered} \text{NaHCO}_3+CH_3COOH\text{ }\rightarrow CH_3\text{COONa}+CO_2+H_2O \\ \text{Baking soda + Vinegar }\rightarrow\text{Sodium acetate}+\text{Carbon dioxide + Water} \end{gathered}`

We have that 1 mole of Baking soda reacts with one mol of vinegar to produce one mole of carbon dioxide. Now, let's define what the actual yield is: Moles of the product that we have during the experiment.

Now, we have a relation between the moles and the volume. 1 mol CO2=24 L CO2. If we have the collected volume of CO2=340mL, the moles will be:

`\begin{gathered} \text{MolCO}_2=GivenmLofCO_2*(1molCO_2)/(24LCO_2)*(1L)/(1000mL) \\ \text{MolCO}_2=340mLCO_2*(1molCO_2)/(24LCO_2)*(1L)/(1000mL)=0.014molCO_2 \end{gathered}`

So, the actual yield of carbon dioxide is 0.014mol
