Calculate the theoretical yield of C$_9$H$_8$O$_4$ produced, in grams, when 10.1g of C$_7$H$_6$O$_3$ react with 5.43g of C$_4$H$_6$O$_3$ according to:
C$_7$H$_6$O$_3$ + C$_4$H$_6$O$_3$ $\rightarrow$ C$_9$H$_8$O$_4$ + C$_2$H$_4$O$_2$

Wintergreen oil is produced in the following scheme from 25.0g of CH$_3$OH:
C$_7$H$_6$O$_3$ + CH$_3$OH $\rightarrow$ C$_8$H$_8$O$_3$ + H$_2$O
If 12.5g of C$_8$H$_8$O$_3$ are actually produced and the reaction proceeds to 38.5% yield, what is the theoretical yield, in grams?

Magnesium oxide is produced according to:
2 Mg + O$_2$ $\rightarrow$ 2 MgO
If the percent yield for the reaction is 89.31%, determine the mass of magnesium (Mg) required to make 30.0g of magnesium oxide (MgO). (note: the 30.0g is an actual amount
and not a theoretical one.)
