#N_A# #xx# #0.150*mol#, where #N_A# #=# #"Avogadro's number"#.

Explanation:

#N_A# #("Avogadro's number")# #=# #6.022xx10^23*mol^-1#. This is simply another number like a dozen or a score or a century or a gross or a thousand or a million. It has the property that #N_A# #""^1H# ATOMS has a mass of #1.00# #g# precisely.

So, the answer is simply: #0.150*molxx6.022xx10^23*mol^-1# #=# #??# mercury atoms.

What is the mass of this number of mercury atoms?
