- Homework Statement
- Compute the specific surface energy in J/g for a 1-gram 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
