m=mols/L first, get the no. of moles. n=wt/mw where n = no. of moles wt = weight mw = molecular weigth n = 5.0g / 40 g/mol cancel the grams, so the left unit is mol. Ans. n=0.125mol You can now get the molarity of the solution, m = n/L where m = molarity m= 0.125mol / 200ml *...

Okay, so using the ground level for your reference point if you went under the crust the GPE must be negative for the total energy to remain zero? I think I get it! Thanks a lot!

How is it possible for gravitational potential energy to be negative? I Googled the answer, but all I could understand was that if the PE was zero at infinity as you move toward an object with gravity the KE must be positive because KE is the energy of motion so the the PE ...

Thanks a lot, we didn't get that formula. That might be why I was having problems. :)
