This picture shows a unit cell model of NaCl. This model has a height width length of 56mm.
56mm is also 56,000,000 nanometers also 560,000,000 angstroms and also 0.056 meters.
The average mass of one grain(cube) of salt is roughly 5.85 x 10^-15 (various per grain) (according to: http://wiki.answers.com/Q/If_a_typical_grain_of_salt_has_a_mass_of_0.3_mg_how_many_unit_cells_does_it_contain)
Given the weight in grams of 5.85x10^-15 we estimate that one grain of NaCl has 1.66x10^-8 moles of NaCl.
We determined that the dimensions of one unit cube of salt to be about 5.86x10^-5 meters which i feel may be a little large. I will be double checking these numbers at a later time.
