Answer:
The answer is [tex]4.4*10^1^0 planets[/tex]
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
[tex]=6.022*10^2^3 * 400\\=2.40*10^2^6[/tex]
2. Now we will find the surface area of earth
[tex]Area = 4\pi R^2[/tex]
The radius of earth is 2.1 x 10^7 Feet
substituting values
[tex]Area = 4*3.14*(2.1*10^7)^2\\Area = 5.5*10^1^5ft^2[/tex]
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
[tex]= 2.40 * 10^2^6/5.5*10^1^5\\=4.4*10^1^0 planets[/tex]
