The mole is the unit of measurement in the International System of Units (SI) for amount of substance. The unit is defined as the amount of a chemical substance that contains as .... stoichiometry of compounds, and the use of atomic masses attracted a large consensus by the time of the Karlsruhe Congress (1860).
For example, one mole of grapefruits would be as big as the earth. ... However, most chemical writing uses mol/dm3, or mol dm-3, which is the same as mol/L.

Oct 20, 2010 ... I like fill-in-the-blank days. However, there is a problem with mole day. Mole day is, of course, 10/23. You know, a mole? One mole is 6.02 x 10 ...
Would it not make more sense to define a mole as 1.0 x 1023 things, a nice ( albeit large) integer that everyone can easily remember? To understand why the ...
The goal of this project is to understand just how big a mole is. In this project, you will compare a mole of a familiar object to something with a huge magnitude.
