Consider the equation: 
. The molar mass of B is 50.0 g/mol. Which of the following statements is true when equal masses of A and B are reacted?
A) If the molar mass of A is greater than the molar mass of B, then A must determine how much C is produced.
B) If the molar mass of A is less than the molar mass of B, then A must determine how much C is produced.
C) If the molar mass of A is the same as the molar mass of B, then A and B react in a perfect stoichiometric ratio and both determine how much C is produced.
D) If the molar mass of A is greater than the molar mass of B, then B must determine how much C is produced.
E) If the molar mass of A is less than the molar mass of B, then B must determine how much C is produced.
