Smallest cube lattice is a 3x3 interlocking Face centred cubic structures. Having 27 atoms, i.e. 13.5 NaCl molecules.
Since there are 6x10^23 molecules in one mol.
If we divide this number by 13.5. We get the fractional volume of our 26.58cm^3 mol of NaCl.
6x10^23/13.5 = 4.44x10^22...
Homework Statement
Show that the bond length for sodium chloride is 0.28nm given that it has a relative density of 2.2, sodium has an atomic weight of 23, and chlorine 35.5. Avogadro's number is 6.0x10^23

The Attempt at a Solution
I've tried many things but...
Ok that makes more sense... But of what consequence does the colour of the LED have in relation to the incident light source colour/wavelength.
Would shining a laser into a non diffused coloured LED (like those ultra bright ones) have still created a current?
Right. Here's how it is, in the past I measured approximate laser power output using diffused LEDs of similar colour wavelength as the laser I was measuring. A multimeter across the terminals showed a current which was proportional to the power of the laser.
I once asked my physics teacher...
