1.
A cube of gold that is 1.00 cm on a side has a mass of 19.3 g. A
single gold atom has a mass of 197.0 amu. a.) How many gold atoms
are in the cube? b.) From the infor given, estimate the diameter in
angstroms of a single atom.
2. An atom of tin (Sn) has a diameter of about 2.8 x 10^-8 cm. a.)
What is the radius of a tin atom in angstroms and in meters (m)? b.)
How many Sn atoms would have to be placed side by side to span a
distance of 6.0 micrometers? c.) If you assume the tin atom is a
sphere, what is the volume in m^3 of a single atom?
I know, I know, it's a lot of problems. So if you can, please do the ones that you well can. I would appreciate a little explanation too. Thanks in advance. =)
