E)2.99 g

Question

Quizplus · Accepted Answer

The total mass of compounds A and B at the beginning of the reaction is:

9.11 g + 8.82 g = 17.93 g

After the reaction is complete, the remaining mass of A and B is:

1.38 g + 1.61 g = 2.99 g

Therefore, the mass of products produced is:

17.93 g - 2.99 g = 14.94 g

So, the correct answer is choice C.
