Consider the Following Balanced Equation: A(g) + 5B(g) $\rightarrow$ 3C + 4D
When Equal Masses of a and B

Consider the following balanced equation: A(g) + 5B(g) $\rightarrow$ 3C + 4D
When equal masses of A and B are reacted, which is limiting?

A) If the molar mass of A is less than the molar mass of B, then B must be limiting.
B) If the molar mass of A is greater than the molar mass of B, then B must be limiting.
C) If the molar mass of A is less than the molar mass of B, then A must be limiting.
D) If the molar mass of A is greater than the molar mass of B, then A must be limiting.
E) More information is needed.
