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
