Why are familiar objects such as pens and paper clips not commonly counted in moles?

One mole is equal to avagadro number

Avagadro's number = 6.023 X 10^23

So it is a big big number. For pens or paper clips we do not need such big unit to express any figure.

Hence we cannot count the normal pens or pencils type macro objects in terms of moles

The mole is used for atomic level particles where in a small amount such large number of identities are present

first one is the correct answer

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
