2021年11月26日 · Atomic mass of Xenon is 131.293 u. Note that each element may contain more isotopes. Therefore this resulting atomic mass is calculated from naturally-occurring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.

Find atomic masses: look up the atomic masses of each element present in the compound. The atomic mass is usually found on the periodic table and is given in atomic mass units (amu). Calculate molar mass of each element: multiply the atomic mass of each element by the number of atoms of that element in the compound.

xe 原子的质量单位是千克（kg）。在科学研究中，通常使用原子质量单位（amu）来描述原子的质量。1 amu 约等于 1.66×10^-27 kg。因此，xe 原子的质量约为 131 amu。 正文： I.引言 xe 原子，即氙原子，是一种稀有气体元素。它属于周期表中的第 18 族元素，原子序数为 54。

2025年1月22日 · The molar mass of Xe is calculated as the sum of the atomic masses of its constituent atoms. Since Xe is monatomic, its molar mass is simply: Molar Mass = 131.293 amu Isotopes of Xe and Their Molar Masses. As mentioned earlier, Xe has multiple isotopes with varying molar masses. Here is a table summarizing the most common ones:
