It seems that there was an attempt to reference a graph that is not visible to me. To answer your question regarding how many grams of Na (sodium) and O3 (ozone) can dissolve in 100 grams of water at 25°C, the solubility of each substance must be known.
Generally speaking:
- Sodium (Na) has very low solubility in water and often doesn't easily dissolve under standard conditions as it reacts with water.
- Ozone (O3) is somewhat soluble in water, but specific solubility can vary.
If you provide specific values or a description of the graph, I can give you a more accurate answer. If you meant to ask for specific values based on common solubility data, O3 can dissolve around 0.5 to 1 grams per liter, and since that is a relatively low solubility compared to common salts, 80 grams or more would be too high for O3.
For the exact answer, please include the relevant data or values from the graph you are referring to.
