How do you determine the average atomic mass
WebJan 30, 2016 · Explanation: You will have to look up the isotopic distribution of lithium nuclei. ALL lithium nuclei have 3 positively charged nuclear particles, protons, i.e. Z = 3. These 3 particles give rise to the element's identity. If you take the weighted average of ALL lithium nuclei, we get an average mass of 6.941 g ⋅ mol−1. Answer link WebTogether, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the …

WebThe atomic mass is sort of an average of all of the different isotopes of an element. Mercury's atomic mass is 200.59, but we can round that to 201 (this is known as the mass number). This is a tally of the total number of particles in an atom's nucleus, so an 'average' atom of mercury contains 201 particles in its nucleus. WebNumber of Neutrons (N): Atomic Mass: u. Atomic Mass (SI): x10 -27. Mass Number: Atomic Symbol: The average atomic mass can be calculated by multiplying the mass number and Natural abundance of each of the isotopes and then adding them all together. You can convert the percentage abundance by dividing it by 100.
