• each group will focus on one half of the data range
• GROUP A = 3.0 g – 8.5 g
• GROUP B = 8.5 g – 14.0 g
• NOTE: each group can pick the amounts as they wish within the assigned range but they should record the amounts according to the available balances (proper digits)
• Q: what factors impact solubility?
• Q: why does temperature impact this?
• Q: how does this look on a “particle level”?

Homework

• ENTER DATA BEFORE WEDNESDAY
• calculations, analysis, conclusion in LNB (by Thursday)
• NOTE: no typed entries in the LNB (OK to cut and tape graph from Excel)
