No I am not talking about the small burrowing animal. No, today I am talking about the measurement. A mole is a base unit of measurement used to measure physical quantity. The unit for a mole is mol (ex. 5 mol of Carbon) It is most commonly used to define the amount of atoms or molecules in substance. In a mole of any element or compound there are 6.02214179(30)×1023 element entities (Often atoms or molecules). That number is known as Avogadro’s Constant. For example there are the same number of atoms in a mole of iron as a mole of silver.

The easiest way to find the number of moles is to take the mass of the elements in the substance, and divide it by the molar mass of that substance. A mole of an element is typically not that large however when you measure of a mole of anything of visible size the size of it would be massive. Here is an example showing the amount of trips to Alpha Centauri a mole of pennies would take.

Measurements

The approximate distance to Alpha Centauri is 4×10^13 or 40 000 000 000 000 km. A round trip = 8×10^13

The average length of a roll of pennies is 9.1 cm. Each penny roll holds 50 pennies or $0.50
Calculations

0.000091 km x (Na) = a mole of pennies

0.000091 km x (6.02×10^23) = 5.4782×10^20

A mole of penny rolls / The distance to Alpha Centuari = # of trips5.4782×10^20 / 8×10^13 = 6.85×10^6

Rounded = 7×10^6Therefore a mole of penny rolls can make approximately 7×10^6 or 7 000 000 trips to Alpha Centauri, the closest star system to our own.
Copper

(n)x(M)=m

1×63.55=m

m=63.55

Therefore the mass of 1 mol of Copper is 63.55g
