What volume of aluminium has the same number of atoms as 8.0cm^3 of mercury?
Answered by bobpursley
figure out the mass of the mercury..

mass=volumemercury/densitymercury.
then the moles of mercury..
molesHg=massHg/molmassHg

then you want the same moles of al

molesAl=molesHg=massHg/molmassHg

then
volume al=massAl/densityAl=molesAl*molmassAl/densitAl


So if I can put all that togetheer..

volumsAl=molmassAl*massHg/molmassHg*1/densityAl
=massHg (molmassAl/molmassHg)*1/dsnisty Al
