to find the simplest ratio of moles between n and o, what should you divide by?
0.286
0.543
0.316
0.439

Explanation:

Step1: Recall mole - ratio concept

To find the simplest ratio of moles between two elements (in this case N and O), we divide the number of moles of each element by the smallest number of moles among them. Without knowing the actual moles of N and O, we assume that the given numbers are the number of moles of either N or O, and we need to divide by the smallest number to get the simplest ratio.
Among 0.286, 0.543, 0.316 and 0.439, the smallest number is 0.286.

Answer:

0.286
