Answer:
The answer is 
Step-by-step explanation:
We ll have to find more information first to solve this question.
1. One mole = 6.022 x 10^23
Assuming one gallon of paint covers the 400 sq ft of area.
Thus total area which can be covered by 1 mole of gallon is

2. Now we will find the surface area of earth

The radius of earth is 2.1 x 10^7 Feet
substituting values

3. Now we will find out the number of planets of earth size which can be covered by mole of gallon of paint
= Total area one mole of gallon can cover / area of earth

The simplified expression is 11r+2
