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 relationship between atomic mass and average atomic mass?
The average atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. It is, the mass of an atom of the substance, rescaled so that carbon-12 would have a mass of 12.
Is 95 the sum of integers between 1 and 500?
No. The sum of all integers between 1 and 500 is 124,749.
Why atomic mass of chlorine is 35.5?
Because chlorine atoms occur as two isotopes: 35Cl and 37Cl. The first accounts for 75.76% of chlorine and the second for the rest so the [weighted] average mass is(75.76*35 + 24.24*37)/100 = 35.48 = 35.5, approx.
How does the speed of light in the fiber compare with the speede of light in the outer covering?
The speed of light in the fibre is greater. As a result, light moving toward the outer covering is refracted back towards the core.
What is Negative 3 divided by zero equal to?
it isn't possible. try it on your calculator cuz it won't work. you can divide 0 into things but you can't divide somthing into 0. or else itz the other way around. 8p
What is a quadrilateral with 4 congruent sides and 2 obtuse angles?
It is a rhombus which also has 2 acute angles
Does dividing by zero result in an imaginary number?
No. Dividing by zero is undefined. It does not result in anything.
What is a experimental constant?
There are potential variables that are kept constant for each trial in a set of trials.
The binary number 11100010 converts to 226 in Decimal and E2 in hex.
What is the speed of light in a vacuum such as space in equation form?
The Equation is:
c = K where
'c' = the speed of light
'K' = a constant = 299,792,458 meters/second
What is the difference between atomic mass and relative atomic mass?
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in atomic mass unit(amu) or Dalton unit or grams/mol.
Relative atomic mass is also the relative mass but does not have a unit but a ratio number.
1 600 000 000 000 000 000 000 meters equals how many zettameters?
The number 1,600,000,000,000,000,000,000 in meters would equal out to be 1.6 zettameters. This is a math problem.

Process: Determine how the given information relates to what is required.
Equation: Formulate what is understood about the relationship between what is given and what is required as an equation.
Solve: Solve the equation.
Answer: State the result of solving the equation in the original terms of the problem.
The atomic mass number of Sulfur is 32.066. Atomic number: 16. Symbol: S
Yes, from the back of the head to the beginning of the tail. Then the length of the tail.
What is the relationship between avogadros number and one mole of any substance?
A mole of any substance has the Avogadro's number of such units. As an example, a mole of hydrogen atoms is equivalent to 6.022 x 1023 atoms.
What is Carbon-12 atomic mass?
12. The number 12 refers to the atomic mass. More precisely, to the sum of neutrons + protons; but this is usually close to the atomic mass. In the case of carbon-12, it is exact, by definition.
