Avogadro Question in Chem A Level Help
Calculate the mass, in kg, of a single 52Cr+ ion.
Assume that the mass of a 52Cr+ ion is the same as that of a 52Cr atom.
(The Avogadro constant L = 6.022 x 1023 mol−1)
From AS 2016 paper. Thanks for any help!

Would you do avogadro constant/ 52?

Would you do avogadro constant/ 52?
Mass = 52 / 1000 / 6.022x1023
Mass = 8.6(4)x10-26
This is the answer given in the mark scheme but I don't understand what they did.

Okay so its 1000 because they want it in kg and the avogadro constant is 1g of it. So its the mass number / 1000 / avogadros constant.
