# The burning of 18.0 g of carbon produces 55.0 g of carbon dioxide. What is the theoretical yield of CO_2? How do you calculate the percent yield of CO_2?

We need a stoichiometric equation:

$C \left(s\right) + {O}_{2} \left(g\right) \rightarrow C {O}_{2} \left(g\right)$

#### Explanation:

And, given the $1 : 1$ $\text{stoichiometry,}$

%"yield"="Moles of carbon dioxide"/"Moles of carbon"xx100%

=((55.0*g)/(44.01*g*mol^-1))/((18.0*g)/(12.011*g*mol^-1))xx100%=83%
