Answer:
60 g/100 g water
Explanation:
Find 5 °C on the horizontal axis.
Draw a line vertically from that point until you reach the solubility curve for CaCl₂.
Then draw a horizontal line from there to the vertical axis.
The solubility of CaCl₂ is 60 g/100 g water.
I don’t know if I am right but I think it is symbol for the first one and the second one is formula.
problem identification
hypothesis
experimentation
data collection and analysis
data interpretation
