Well, a quick glance at the Periodic Table tells us that nickel has a molar mass of #58.7*g*mol^-1#...

Explanation:

And given the context, what does this mean?

It means that #6.022xx10^23# individual atoms of nickel metal have a mass of #58.7*g#...i.e. #6.022xx10^23# is the molar quantity...

And so we take the product of the quotient....

#(9.20xx10^25*"nickel atoms")/(6.022xx10^23*"nickel atoms"*mol^-1)xx58.7*g*mol^-1=?*g#.....

I gets a mass of approx. #9*kg# nickel metal....
