test 2 question 3 part C (X-ray)

Postby 905085650 » Sat Dec 08, 2018 8:24 pm

What is the mass that we use for De Broglie's in this part of the problem? Is it just the weight of the electron or the weight or the electron scaled up with Avogadro's number because it said 1 mol of electrons in part A?

Thank you!!

It is just the weight of the electron. You use Avogadro's number when pulling molecular weights from the periodic table because the periodic table is in moles per substance and we need grams of a substance.
