Homework Statement


one ounce of gold (taken to be 28.35g) can be pulled or drawn into a monofilament wire that can be up to 50km in length

true or false

support your argument with some evidence

Homework Equations


atomic mass of gold ,Au= 196.96
avagardo's number=6.02x1023 atoms/mole
approx. radius of a single gold atom r=10-10 m
volume of sphere=4XpieXr3/3


The Attempt at a Solution


one ounce of gold X atomic mass ?

Welcome to the PF!

What is the volume of 1oz of gold? What is a reasonable diameter for a thin monofilimanet wire? What would the volume be of such a wire at the length asked about in the question?
 
a reasonable diameter for the monofilament could be 0.25? work out the volume of this and times and times the answer by 50 ?

0.25 what, for goodness sake?!

And you don't multiply volume by distance to get volume again...
