#"1 mole"# of tin has a mass of #118.71*g#; there are #6.022140857(74)xx10^23# individual atoms of tin in #1# #mol#

Explanation:

And thus,

#"Moles of tin"# #=# #(8.800xx10^25" tin atoms")/(6.022xx10^23" tin atoms mol"^-1)#

#~=# #146*mol#

And thus #"mass of tin atoms"# #=# #118.71*g*mol^-1xx146*mol# #=# #"over "17*kg# of tin metal.
