Question

Give the percent yield when 5.64 g of co2 are formed from the reaction of 4 moles of c8h18 with 4 moles of o2 and 28.2 of co2 were expected to be formed if the experiment worked perfectly

Answer 1

Answer : The percentage yield $CO_2$ is 20%.

Solution : Given,

Actual yield of $CO_2$ = 5.64 g

Theoretical yield of $CO_2$ = 28.2 g

The Net balanced chemical reaction is,

$2C_8H_{18}+25O_2\rightarrow 16CO_2+18H_2O$

Formula used for percentage yield :

$\text{ Percentage yield}=\frac{\text{ Actual yield}}{\text{ Theoretical yield}}\times 100$

$\text{ Percentage yield of } CO_2}=\frac{5.64g}{28.2g}\times 100=20%$

Therefore, the percentage yield $CO_2$ is 20%.
