#1# #"mole"# of nickel has a mass of #58.69# #g#.

Explanation:

Clearly, #4.50# #"moles"# of #Ni# has a mass of #4.50# #mol# #xx58.69*g*mol^-1#, which is approx. #270# #g#. If you are talking about American currency, I am pretty sure that nickels (and dimes and quarters) are not so massive.

It is a fact that if there are #1# #"mol"# of stuff, there are #6.022xx10^23# items of that stuff. So you do the arithmetic.
