I attached the solubility curve.
Answer:
solubility of KBr at 80°C is 100
Step-by-step explanation:
In the given graph, the x-axis represents the temperature while the y-axis represents the solubility.
Therefore, we will read the graph as follows:
1- Find the KBR curve which is the green one
2- Find the point on that line that corresponds to temperature = 80°C
3- Read the corresponding value of the solubility
Hope this helps :)
