What is the solubility of solid W in water at 100°C?

The solubility of solid W in water at 100°C is measured by how much of the solid dissolves in a specific volume of water at this elevated temperature. In this case, the correct value of 21.5 g/100 mL indicates that at 100°C, a maximum of 21.5 grams of solid W can dissolve in 100 milliliters of water.

This solubility value suggests a solubility that is relatively significant, which is common for many salts and organic compounds as temperature increases; solubility often increases with temperature, allowing more of the solid to dissolve. Understanding solubility in this context is important as it reflects the capacity of the solvent (water in this case) to dissolve a solute at a given temperature, influenced by molecular interactions and thermodynamic principles.

Each of the other values for the solubility of solid W either underestimates or overestimates the actual solubility. It is essential to utilize experimental data or solubility charts for accurate references when determining these values. Thus, the choice of 21.5 g/100 mL as the solubility of solid W at 100°C is consistent with typical solubility behaviors observed in
