The following table represents a solubility of a few nonpolar gases in water at 25 degrees Celsius under a total pressure of 1.0 atmospheres. Based on the information provided, what is the most likely solubility value of f 2? So if we take a look here, we have n 2, 0 2, and f 2. N 2 has a solubility of 0.6 millimolar, o 2 has 1.2 millimolar, and f 2 is what we need to find. If If you look on your periodic table, you'll see that nitrogen is in group 5A, oxygen is in group 6A, and then fluorine is in group 7A. From the pattern that we see, going from nitrogen to oxygen, we can see that the solubility is increasing. Okay? Now this partly is due to the fact that oxygen, o two weighs more than n 2, and therefore, it's going to be more soluble because it connects 2 ideas such as, intermolecular forces. Now here we're going to say that going from n 2 to o 2, the mass is increasing so our solubility increases, and we can see that it increases by a lot, it goes from 0.6 to 1.2. Following this pattern, we should expect the solubility to keep on increasing if we go from 0 2 to f 2. So we should expect the solubility to be higher than 1.2, which means that a and b are out. Now, going from n 2 to o 2, there was a big increase. So we should expect that continued pattern. There should be a big increase going from 0 2 to f 2. C wouldn't work because going from 1.2 to 1.3 is not a big enough increase, So the best answer here would be option d, 4.2 millimolar for the solubility of f
