Answer:

Well, #6.022xx10^23# #"zinc atoms"# have a mass of #65.4*g#.

Explanation:

Of course, #6.022xx10^23# #"zinc atoms"# constitutes a mole of #"zinc atoms"#, and we say that zinc metal has a molar mass of #65.4*g*mol^-1#.

So we take the quotient:

#(1.807xx10^24" zinc atoms")/(6.022xx10^23" zinc atoms"*mol^-1)xx65.4*g*mol^-1~=200*g#
