A chemist is studying the relationship between temperature and the solubility of a salt (Salt X) in water. The following table summarizes the solubility (in grams per 100 mL of water) of Salt X at various temperatures:
Temperature (°C) | Solubility (g/100 mL) |
---|---|
0 | 10 |
20 | 20 |
40 | 30 |
60 | 45 |
80 | 70 |
Based on this table, what is the increase in the solubility of Salt X in grams per 100 mL when the temperature is raised from 40°C to 80°C?
