What is the mass of one mole of electrons? Mass of one electron is 9.1 x 10 -31 kg<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
To calculate the mass of one mole of electrons, we need to multiply the mass of a single electron by Avogadro’s number.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n\n
Mass of an electron<\/strong>: The mass of a single electron is extremely small, on the order of 10\u221231\u2009kg10^{-31} \\, \\text{kg}10\u221231kg. This value is crucial because it represents the smallest mass in terms of elementary particles.<\/li>\n\n\n\n
Avogadro’s number<\/strong>: Avogadro’s number, 6.022\u00d710236.022 \\times 10^{23}6.022\u00d71023, is the number of particles (atoms, molecules, electrons, etc.) in one mole of a substance. This constant allows us to convert between the microscopic world (individual particles) and the macroscopic world (grams or kilograms).<\/li>\n\n\n\n
Calculating the mass of one mole<\/strong>: To find the mass of one mole of electrons, we multiply the mass of a single electron by Avogadro’s number. The result, 5.48\u00d710\u22127\u2009kg\/mol5.48 \\times 10^{-7} \\, \\text{kg\/mol}5.48\u00d710\u22127kg\/mol, indicates that one mole of electrons weighs about 5.48\u00d710\u221275.48 \\times 10^{-7}5.48\u00d710\u22127 kilograms, or 0.548 milligrams.<\/li>\n<\/ol>\n\n\n\n
Conclusion:<\/h3>\n\n\n\n
Thus, the mass of one mole of electrons is approximately 5.48\u00d710\u22127\u2009kg5.48 \\times 10^{-7} \\, \\text{kg}5.48\u00d710\u22127kg, which shows that the mass of electrons is incredibly small compared to macroscopic objects we encounter in everyday life.<\/p>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
