A mole of 1 gallon cans of paint could cover every square inch of the surface of how many planets the size of the earth?
Nady [450]

Answer:

The answer is 4.4*10^1^0 planets

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

=6.022*10^2^3 * 400\\=2.40*10^2^6

2. Now we will find the surface area of earth

Area = 4\pi R^2

The radius of earth is 2.1 x 10^7 Feet

substituting values

Area = 4*3.14*(2.1*10^7)^2\\Area = 5.5*10^1^5ft^2

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

= 2.40 * 10^2^6/5.5*10^1^5\\=4.4*10^1^0 planets

<h3>Factoring</h3>

In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization.  One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.

You should factor the given expression.

2-\frac{x+3}{x+1}-\frac{x-5}{x-1}\\ \\ 2+\frac{-\left(x+3\right)\left(x-1\right)-\left(x-5\right)\left(x+1\right)}{\left(x+1\right)\left(x-1\right)}\\ \\ \mathrm{Apply\:the\:fraction\:rule}:\quad \:a+\frac{b}{c}=\frac{ac+b}{c}\\ \\ \frac{2\left(x+1\right)\left(x-1\right)-\left(x+3\right)\left(x-1\right)-\left(x-5\right)\left(x+1\right)}{\left(x+1\right)\left(x-1\right)}\\ \\ \frac{2x+6}{\left(x+1\right)\left(x-1\right)}=\frac{2x+6}{x^2-1}
