Suppose you have 897 sheets of paper. how many moles of paper do you have?

Consider the following definitions.
1 doz = 12
1 gross = 144
1 ream = 500
1 mol = 6.022×1023
Suppose you have 897 sheets of paper.

Explanation:

1 mole of a substance is defined as the amount of substance containing a number of units of the substance equal to the Avogadro number:

This means that 1 mole of paper will contain a number of sheets equal to the Avogadro number,

In this case, instead, the number of sheets in this amount of paper is

N = 897

Which corresponds to n moles.

Therefore, we can solve the problem by using the rule of three:

And solving for n,
