Graphing is an essential skill used throughout chemistry courses and other sciences.
Here is aproblem dealing with the creation and use of a graph.
The solubility, S, of K2SO4 is given as grams K2SO4 per 100.0 g of H2O (that is, the
number of grams of K2SO4 that will dissolve in 100.0 g of H2O to form a saturated solution).
The experimentaldata are:

a. On graph paper, plot the solubility (ordinate, or y-axis) versus the temperature
(abscissa, or x-axis). Follow the points outlined in your Lab Manual on plotting data.
Your plot must include labeled axes (showing necessary units), and a title (such as
"Solubility of K2SO4 in Water as aFunction of Temperature"). Spread out your data (that
is, "expand the axes") so that your plotcovers a large portion of the page of graph
paper. Use your graph to answer the questions below.
b. Determine the mass of K2SO4 that will dissolve in 250.0 g of H20 to form a
saturatedsolution at 70.0 °C.
C. Determine the temperature at which 67.5 g K2SO4 will dissolve in 450.0 g H20
to forma saturated solution.
d. Determine the mass of K2SO4 that will crystallize when 500.0 g of a saturated
solutionat 100.0 °C is cooled to form a saturated solution at 20.0 °C.
e. Determine the mathematical equation that describes 'S' as a function of 'T'.
