Explanation / Answer
Question #1:
IF:
Hexane density: 0.655 g.mL-1
Aq. solution density : > 0.655 g.mL-1 (because is any solute in water)
THEN:
Aq. solution Layer is botton because it is more heavy that Hexane layer, and haxane layer is top because density is low in relation with aq. solution.
Question #2:
Normal equation: 1 moL Ca
