The Avogadro Constant is 6.02 x 1023 What is a mole? One mole of a substance is the amount of the substance that contains 6.02 x 1023 particles. The particles measured can be atoms, molecules, electrons or ions. National Mole Day is celebrated on the 23rd October each year. Amadeo Avogadr...

After the revision of the SI to be implemented in 2019, when all SI units will be based solely on constants, the mole will be defined through a fixed value of the Avogadro constant NA. One mole contains exactly 6.02214076 × 1023 elementary entities, meaning the mole will no longer be ...
The main subject of the workshop will be the determination of the Avogadro constant through the measurement of the molar and atomic volume of single crystal silicon, but other methods will be analysed and discussed and experimental results compared with estimates obtained from the adjustment of the...
An improved attempt of several national metrology institutes to replace the present definition of the kilogram with the massof a certain number of 12C atoms is described. This requires the determination of the Avogadro constant, NA, via the silicon route with a relative uncertainty better than 2 ...
