 Homework Statement:

Compute the specific surface energy in J/g for a 1gram cube of table salt with an edge of 0.77 cm, when it is split into
(a) 1 µm side cubes
(b) 1 nm side cubes
(c) 1nm radius sphere
 Relevant Equations:
 NaCl: Surface energy, γ = 0.2 J/m^2 ; Edge energy, E = 3 x 10^11 J/m
I got these values but I wanted to make sure I was doing it the correct way
a) 0.548 J/g for system of 1 µm cubes
b) 9.131 x 10^19 J/g for system of 1 nm cubes
c) 273.890 J/g for system of 1 nm radius spheres
