Methanol (CH4O), which is used as a fuel in high-performance racing cars, burns in the presence of O2 to form CO2 and H2O. The molar masses for all substances are given under the balanced equation. 

2CH4O (l)       +   3O 2 (g)         →   2CO 2 (g)        +  4H 2O(g) 

32.04 g/mol       32.00 g/mol       44.01 g/mol        18.02 g/mol 

a. What is the theoretical yield of CO 2 from 35.0 g of methanol? 

b. What is the percent yield of CO 2 if 26.8 g of CO 2 are formed?
