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(s) + O_2(g) rarr CO_2(g)#

Explanation:

And, given the #1:1# #"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%#
