Water can hold 36 grams (g) of salt in every 100 milliliters (ml). the ocean contains 3.6 g of salt in every 100 ml. as a solution, which is seawater? a. resaturated b. supersaturated c. saturated d. unsaturated

From the statement "water can hold 36 grams (g) of salt in every 100 milliliters (mL)", we can solve for the solubility of salt in water. 

Solubility = 36g / 100mL = 0.36 g / mL

The ocean contains 3.6 g of salt in every 100 mL or 0.036 g / mL. Therefore, it unsaturated. There is less salt in the water which means it can dissolve more until the concentration would be 0.36 g/mL.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
