Answer
$9 \times 10^{13}\text{ dollars}$
Work Step by Step
A mole is a unit of measurement used in chemistry to express amounts of a chemical substance. It is defined as Avogadro's number of entities (such as atoms, ions, or molecules) and it is equal to $6.022 \times 10^{23}$. A mole of U.S. dollar bills is not the same as a mole of a chemical substance and it is not a standard unit of measurement.
If you had a mole of U.S. dollar bills and distributed the money equally to all of the people in the world, each person would receive $$\frac{6.022 \times 10^{23}}{7\times 10^9} \approx 9 \times 10^{13}\text{ dollars}.$$ It is important to note that this is a purely hypothetical scenario and the actual distribution of wealth in the world is much more complex and unequal.
