According to this Source: http://classics.honestjohn.co.uk/how-many-survived/BMW/7-series
BMW E23s were made from 1977 to 1985, so from year by year, here's how many are left (including SORN):
1977 - 1979: 18
1980: 7
1981: 15
1982: 23
1983: 35
1984: 40
1985: 58
This puts the total of about only 196 left as of 2013! It might not sound like a very rare amount, but then when you think there are about 40 million cars in total in the UK...
E23 can be a cell reference, referring to the 23rd cell in column E. E23, or any cell reference, can be used in formulas.

E23 Communication Error: There is a vehicle/radio communication problem or an inter radio communication problem, Correction: Disconnect battery voltage to the radio and then reconnect after a few minutes.
Aluminum sulfide has a molar mass of 150.16 grams per mole. This means there are 0.666 moles present, or 4.01 E23 molecules. Each molecule of Al2S3 has 2 aluminum atoms, so there are 8.02 E23 atoms of aluminum present.

That is called Avogadro's number. It is the number of particles in a mol.
1mol S = 6.022 E23 atoms S 3.7mol S x 6.022 E23 atoms S/1mol S = 2.2 E24 atoms S Since the superscript and subscripts are not working, I used E to represent "x 10", followed by the exponent like you might find on a calculator.
A mole of a substance has 6.022 E23 things of that substance. So 3 moles of Carbon-12 has 1.806 E 24 atoms.
One mole of a substance has 6.022 E23 units. This means that in .75 moles there are 4.52 E23 molecules.
