describe how you would perform an experiment to establish the
relationship between the solubility of NaSoO4 in water and the
temperature of the water

The question states NaSO4 but i suppose it must mean Na2SO4

I found the following detailed description (for another salt) for such
an experiment for you:
"The Effect of Temperature on Solubility"
( )

The idea is to solve weighed samples of the salt in water, heat the
solution and then watch for the appearance of solid in the solution:

Students are given weighed samples of a soluble salt such as potassium
nitrate. The sample is added to 20 mL of water and heated until all of
the salt dissolves. The solution is cooled, and the temperature at
which solid appears is noted. A solubility curve is prepared by
pooling the data from all of the students."
(see above)

All you got to do is find out reasonable amounts of Na2SO4 for the
amount of solvent by making a supersaturated solution.

I hope this help you to solve the problem.

A chemical with that formula does not exist.
Did you mean Na2SO4 ?
