Question

You have a pure (24-karat) gold ring with mass 26.2 g. Gold has an atomic mass of 197 g/mole and an atomic number of 79. Avagadro's number is 6.02*10^23 atoms/mole. a) How many protons are in the ring? b) What is their total positive charge (in Coulombs, C)? c) If the ring caries no net charge, how many electrons are in it? d) If the density of gold is 1.93*10^4 kg/m^3, what is the volume of the ring? e) What is the charge density of the protons in the ring (in p+/m^3)? IMPORTANT NOTE: In the last part of this, the units are asking for proton density (p+/m^3), not charge density (C/m^3).

Explanation / Answer

you have the mass in grams the atomic mass in grams per mole the atomic number in number of protons per atom and avogadro's constant, 6.023*10^23 in atoms per mole i'm sure you can rearrange these into an equation to give an answer in protons. ______________________________________… I'm not going to do your homework for you, you have the information you need to answer these questions. The part of this that you are going to learn from is figuring out, BY YOURSELF, how to use the information you have to answer the questions you've been asked
