Understanding how solubility varies with temperature and pressure

    

A pair of 100 mL samples of water are taken from a well bored into a large underground salt (NaCl) deposit.

Sample #1 is from the top of the well, and is initially at 32 °C. Sample #2 is from a depth of 50. m, and is initially at 42 °C. Both samples are allowed to come to room temperature (20. °C) and 1 atm pressure. An NaCl precipitate is seen to form in Sample #1.

A bigger mass of NaCl precipitate will form in Sample # 2.

A smaller mass of NaCl precipitate will form in Sample #2.

• The same mass of NaCl precipitate will form in Sample #2.

No precipitate will form in Sample #2.

I need more information to predict whether and how much precipitate will form in Sample #2.
