Post Mod #28 pt b: conversion units [ENDORSED]

[Annie Lieu-1H]

The question asks for the energy required to remove an electron from the sodium atom. But the work function is given in units of kg*mol^-1. I know that a joule's SI base units is ‎kg⋅m2⋅s−2. How would I convert that??

Thank you!

The units for the work function will be given in either J or J/mol (or kJ or kJ/mol), but never kg/mol. When you are given the energy/mol, multiply by Avogrado's number to convert the work function in terms of energy/atom.

I am so ashamed that I misread my own handwriting. It was in kj/mol this whole time. Thank you.

Just to clarify, do you multiply or divide avogadro's number?
