17. On the grid provided, mark an appropriate scale on the axis labeled “Solute per 100 g of H2O (g).

18. On the same grid, plot the data from the data table. Circle and connect the points.

19. Based on the data table, if 15 grams of solute is 19.

o
dissolved in 100 grams of water at 40 C, how many

more grams of solute can be dissolved in this solution
o

to make a saturated at 40 C?

20. According to Reference Table G, how many grams 20.
o

of KClO3 must be dissolved in 100 grams of H2O at 10 C

to produce a saturated solution?
