Use the proper methods to answer the following questions:
a) Draw a scatter diagram to show the data.
b) Estimate the temperature based on the mass of X.
c) What quantity might be expected to dissolve at 42 C? Find the quantity that your cquation indicates
would dissolve at 10 C and comment on your answer.
