Answer:
Depends on the reacting molecules.
Explanation:
More molecules of IF3 are formed when more I2 (purple) molecules and F2 (green) molecules combine or react with each other. If one molecule of I2 (purple) react with three F2 (green) molecules then two molecules of IF3 are formed. The equation for this reaction is given below:
I2 + 3F2 -----------> 2IF3. In this reaction, we can see that one molecule of I2 react with three molecules of F2 forming two molecules of IF3.
