Question

It is common in mass spectrometry to assume that the mass
of a cation is the same as that of its parent atom. (b) What percentage of the mass of an 1H
atom does the electron represent?

Accepted Answer

Hi everyone today. We have a question telling us that mass spectrometry, the mass of a cat ion is taken as the mass of the atom from which the cat ion was formed, even though the cat eye on its missing electrons calculate what percent of the mass of a lithium seven atom is represented by two electrons. And is this percentage significant? So the mass of lithium seven is seven 0. 6005 units. And the mass of an electron is 0. zero eight 58 units. So now we're going to calculate the mass percent and that's going to equal two Times 0. 54 units. Because we have two electrons, we're multiplying by two there over 7. units. And we're going to multiply that by 100 because we want a percentage And that equals 0. 64%. So no, this is not a significant percentage. And those are our answers. Thank you for watching. Bye.
