The Avogadro constant (symbols: L, NA) is the number of "elementary entities" (usually atoms or molecules) in one mole, that is (from the definition of the mole), the number of atoms in exactly 12 grams of carbon-12.[2][3] It was originally called Avogadro's number. The 2006 CODATA recommended value is[1]:
The Avogadro constant is named after the early nineteenth century Italian scientist Amedeo Avogadro, who, in 1811, first proposed that the volume of a gas (at a given pressure and temperature) is proportional to the number of atoms or molecules regardless of the nature of the gas.

What are the rules fr multiplication and divisions of integers?
(positive number) x (positive number) = positive number (positive number)/(positive number) = positive number (positive number) x ( negative number) = negative number (positive number)/( negative number) = negative number (negative number) x (negative number) = positive number (negative number)/(negative number) = positive number
What is the formula for the atomic number?
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
What does a negative number multiplied by a negative number equal to?
A positive number. Positive Number x Positive Number = Positive Number Positive Number x Negative Number = Negative Number Negative Number x Negative Number = Positive Number
Can a real number that is not a rational number is a?
A real number which is not a rational number is an irrational number.
How do you find the number of neutrons from the mass number?
To find the number of neutrons from the mass number, subtract the atomic number from the mass number. The atomic number represents the number of protons in an atom, and by subtracting it from the mass number, you can determine the number of neutrons present.

How do you work out how to times a positive number by a negative number?
A positive number times a positive number will always get you a positive number A negative number times a negative number will always get you a positive number (same signs will get you a positive number) but A positive number times a negative number will always get you a negative number or A negative number times a positive number will always get you a negative number (different signs will get you a negative number)
How do you get the mass number by adding neutrons and the atomic number?
The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. The atomic number represents the number of protons in an atom, so adding the atomic number to the number of neutrons will give you the mass number.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
