massfrac即mass fraction,意思是质量分数。 massfrac的基本定义 massfrac是质量分数(Mass Fraction)的缩写,它表示某一物质的质量在总体质量中所占的比例。质量分数是化学、材料科学、工程学等多个领域中常用的一个参数,用于量化分析物质组成或系统状态。质量分数通常以小数或百分比的形...
4.1.1 Mass fractions and mole fractions Mass and mole fraction are the two important components of any specific gas mixtures. They are used to describe gas concentrations as well as to determine the vapor pressures of mixtures of similar liquids. Mass fraction (yi), also known as weight fracti...

Define Molecular mass. Molecular mass synonyms, Molecular mass pronunciation, Molecular mass translation, English dictionary definition of Molecular mass. n. The sum of the atomic weights of all the atoms in a molecule. Also called relative molecular mas
The molar mass for this compound is computed to be 176.124 g/mol. The given number of moles is a very small fraction of a mole (~10-4or one-ten thousandth); therefore, we would expect the corresponding mass to be about one-ten thousandth of the molar mass (~0.02 g). Performing the...
The definition of kelvin for thermodynamic temperature was adopted at the 16th CGMP (in 1967) as follows: The kelvin is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. The triple point of water is, by definition, that single point in the temperature-versus...
