Hello, here’s the answer to your question. Converting ammonia to nitrate, which is absorbed by plants
I believe the answer is compound B may have a lower molecular weight compared to compound A.
At the same temperature, lighter particles of a compound have a higher average speeds than do heavier particles of another compound. Thus, particles of compound B are lighter than those of compound A and thus they have a higher average speed, hence evaporating faster compared to compound A.
0.843 moles would be the answer
