science and technology(CODATA) in 2006 are suggested to be adopted.According to national standards and scholarly customs,the expression of the uncertainty of measurement is presented.To avoid that significance figure has not a uniform definition and hence lead to ambiguity and misunderstanding,rounding ...

By definition, the number of atomic mass units per molecule is equal to the number of grams per mole. Hence, divide 10 by the above result. > 10. 0.1721788580 (2.4) which is the number of moles in the sample. To calculate the number of molecules, multiply the above result by Avogadro...

The present definition of the astronomical unit states that it is the mean distance of the orbit of a fictitious unperturbed planet having the mass and sidereal period that Gauss adopted for the earth in his determination of the gravitational constant k . In the broadest sense, the solar ...

The acid ionization constant is based on theequilibrium reactionbetween an acid and water. In one commonly used definition, acids refer to compounds able to donate hydrogen ions during dissociation in water. When an acid dissociates in solution and a proton (or hydrogen ion) is lost, the corre...
One is the need to have a set of numerical values that can be used reliably in all branches of science and technology. The other is the verification of physical models inherent in the consistency of those values. This paper discusses the definition of 'fundamental constants' and the reasons ...
In PHP, constants are created using the define() function.SyntaxThe basic syntax for defining a constant is as follows:define("CONSTANT_NAME", "constant_value"); Here,define: This is the keyword used to create a constant in PHP. "CONSTANT_NAME": This is the name of the constant. It ...
