When it comes to numbers the mathies have pi and the chemists have the mole.
A mole is a unit in the International System of Units and represents an amount of substance. One mole is equal to 6.02 x 1023 of particles, or of anything that can be counted.
To conclude National Chemistry Week Waterloo’s Chemistry Department is celebrating Mole Day this Friday. This annual event commemorates Avogadro’s Number (6.022141 x 1023) and is celebrated from 6:02 a.m. to 6:02 p.m. on Friday October (10th month) 23rd.
