My possible answers are:

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 A must be limiting.

C) If the molar mass of A is greater than the molar mass of B, then B must be limiting.

D) If the molar mass of A is less than the molar mass of B, then A must be limiting.

E) neither reactant is limiting

I am pretty sure the answer is D. I understand that a limiting reactant is the reactant that runs out first and limits the amount of prodct that can form. Please help!

10 g A

10 g B

molar mass A = 10

molar mass B = 20
