Answer:
Step-by-step explanation:
To calculate the percent yield of the reaction, we need to compare the actual yield of the reaction (11.6 g of CO2) to the theoretical yield of the reaction, which we can calculate using stoichiometry.
The balanced equation for the reaction is:
C + O2 → CO2
From the equation, we can see that the mole ratio of carbon to carbon dioxide is 1:1. Therefore, the theoretical yield of CO2 can be calculated from the mass of carbon used in the reaction:
molar mass of carbon = 12.01 g/mol
moles of carbon = 5.60 g / 12.01 g/mol = 0.466 mol
moles of CO2 produced = 0.466 mol
mass of CO2 produced = moles of CO2 × molar mass of CO2
mass of CO2 produced = 0.466 mol × 44.01 g/mol = 20.5 g
So the theoretical yield of CO2 is 20.5 g.
Now we can calculate the percent yield of the reaction:
percent yield = (actual yield / theoretical yield) × 100%
percent yield = (11.6 g / 20.5 g) × 100%
percent yield = 56.6%
Therefore, the percent yield of the reaction is 56.6%.
