One electron has a mass of  9.10938291 x 10^−<span>31 kg. One mole of electrons contains 6.022x10^23 electrons where half of a mole is has 3.011x10^23 electrons. Therefore, the mass of half a mole of electrons would be 2.74x10^-7. Hope this answers the question. Have a nice day.</span>

An element has an atomic number of 92 and a mass number of 234. how many neutrons does the element have? 192 142 92
GuDViN [60]
The atomic number of an element is characteristic to that element. Atomic number is the number of protons of that element.
Mass number is the sum of protons and neutrons of the element.
since protons and neutrons have a mass of 1 unit each, they together make up the mass of the element.
atomic number - number of protons - 92
mass number - number of neutrons + protons = 234
number of neutrons = mass number - atomic number 
neutrons = 234 - 92 = 142
answer is 142
