Question

What is the theoretical yield of carbon dioxide?

a) 72 g
b) 144 g
c) 36 g
d) 180 g

Answer 1

The theoretical yield of carbon dioxide can be calculated using stoichiometry and the given chemical equation. The balanced equation is 6 CO₂ + 6H₂O → C6H₁2O₆ +6 O₂. From the equation, we can see that 6 moles of CO₂ react to form 1 mole of C6H₁2O₆. The molar mass of CO₂ is 44.009 g/mol and the molar mass of C6H₁2O₆ is 180.156 g/mol. Therefore, the theoretical yield of carbon dioxide is 72 g (option a).

Step-by-step explanation:

The theoretical yield of carbon dioxide can be calculated using stoichiometry and the given chemical equation. The balanced equation for the reaction is:

6 CO₂ + 6H₂O → C6H₁2O₆ +6 O₂

From the equation, we can see that 6 moles of CO₂ react to form 1 mole of C6H₁2O₆. The molar mass of CO₂ is 44.009 g/mol and the molar mass of C6H₁2O₆ is 180.156 g/mol. Therefore, the theoretical yield of carbon dioxide can be calculated as follows:

1. 
   
3. Convert the given mass of CO₂ to moles using the molar mass. Given: 22.0 g CO₂, molar mass = 44.009 g/mol
4. 
   
6. Use the mole ratio from the balanced equation to convert moles of CO₂ to moles of C6H₁2O₆. Mole ratio: 6 mol CO₂ = 1 mol C6H₁2O₆
7. 
   
9. Convert moles of C6H₁2O₆ to grams using the molar mass. Molar mass = 180.156 g/mol

The theoretical yield of carbon dioxide is 72 g (option a).
