When air is hot, the the particles move much faster and when the air is cold the particles slow down as they are condensing

Answer:
the attractions between molecules shift the charges within molecules
a.200.59 amu of mercury contains = 6.02 * 1023 molecules
Mass for 3.0 * 1023 molecules = (3.0 * 1023 * 200.59) /6.02 * 1023
= 100.29 amu
Thus, mass for 3.0 * 1023 molecules is 100.29 amu
b.As, 200.59 g mercury contains = 6.02 * 1023 atoms
1 g mercury contains = (6.02 * 1023 /200) atoms
= 3.01 * 1021 atoms
Thus, 1 ng mercury contains = (3.01 * 1021) / 109
= 3.01 * 1012 atoms
Thus, 3.0 * 1012 atoms present in 1 ng mercury
