Mathematical Constants
Intriguing, ubiquitous, and at times mysterious, numerical constants set the allowable limits for all universal phenomena. Whether your questions involves π, Avogadro's number, Planck's constant, the atomic mass unit, or any of the other multitudes of immutable numbers used in science, this is the category where they should be asked.

What is the golden ratio of a snail shell?
The golden ratio or the Fibonacci number is apparent in many natural objects. This mathematical equation proves that by dividing a line in two parts, the longer part divided by the smaller part is also equal to the whole length divided by the long part.

Biggest number under infinity is grahams, under grahams is googolplex, under googolplex is googol.
How do you calculate effective atomic mass?
Aeff=(Zeff)/((Z/A)eff)
Zeff=wi*Zi
wi is weight fraction in ith element in compound. for example water has 0.112 H and 0.888 O.
(Z/A)eff=wi*Zi/Ai
Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
How big is a 45000 gallon storage tank?
1 US Gallon is 0.133681 cubic foot. So 45,000 Gallons would require a tank of approx 6000 Cu Ft [6 015.625 cubic feet, to be precise]
A standard-sized freestanding circular tank with a 21ft base and height of 17ft 11in has a nominal capacity of 45,000 Gallons.
What is the atomic mass rounded of boron?
Boron - B - Group III
The atomic number is 5.
The mass number is 11.
Atomic mass used in a sentence?
The atomic mass of an element is the weighted average of the masses of all the stable isotopes of the element (if it has any), weighted by the natural occurrence levels of the isotopes in the elements as found on earth or in the atmosphere.
What can the atomic mass tell you about an atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What are the factors to 12 and 70?
12 = 2 X 2 X 3
70 = 2 X 5 X 7
The common factor = 2 x 2 x 5 x 3 x 7 = 420
What best describes an imaginary number?
You can describe it as a number defined such that i squared = -1.You can also define the complex plane first, and then describe an imaginary number as a complex number in which the real part is zero.
