Final answer:
The question asks for how many more grams of potassium chlorate (KClO3) can be dissolved at 70 °C before saturation occurs, but the lack of specific solubility data for KClO3 at this temperature prevents us from providing an accurate answer.
Step-by-step explanation:
To determine how many more grams of potassium chlorate (KClO3) can be dissolved in the solution before it becomes saturated, one would typically refer to a solubility curve for KClO3 at 70 °C. However, since the specific solubility information for KClO3 at this temperature is not provided, we cannot give an accurate answer. The question requires the solubility data of KClO3 at 70 °C to calculate the remaining amount that can be dissolved. Without this crucial piece of information, any attempt to answer the question would be based on speculation rather than facts.
Considering the examples provided for other solutes, a general approach would involve looking at the correct solubility curve for KClO3, finding the solubility at 70 °C, and then subtracting the amount already in solution (10 g) from that solubility limit. Without the appropriate data for KClO3, no further calculations can be performed.
