Question

determine the percent yield for carbon dioxide if 4.50 moles of propane yielded 7.64 moles of carbon dioxide

Answer 1

Percent yield = 57%

Step-by-step explanation:

Given data:

Number of moles of propane = 4.50 mol

Number of moles of carbon dioxide = 7.64 mol

Percent yield = ?

Solution:

Chemical equation:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Now we will compare the moles of propane and carbon dioxide.

C₃H₈ : CO₂

1 ; 3

4.50 : 3×4.50 = 13.5 mol

Percent yield:

Percent yield = actual yield / theoretical yield × 100

Percent yield = 7.64 mol / 13.5 mol × 100

Percent yield = 0.57× 100

Percent yield = 57%
