Question

What is the percent yield for carbon dioxide if 10.0 grams of carbon

Answer 1

The percent yield : 81.5%

Further explanation

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

2CO+O₂⇒2CO₂

mol CO(MW=28,01 g/mol)

$\tt \dfrac{10}{28.01}=0.357$

mass CO₂ (theoretical)(MW=44,01 g/mol)

$\tt 0.357\times 44.01=15.712~g$

the percent yield :

$\tt \dfrac{12.81}{15.712}\times 100\%=81.5\%$
