Answer:

Approx. #15*g#

Explanation:

#"Concentration"# #=# #"number of moles"/"volume of solution"#

Thus #0.250*mol*L^-1# #=# #n_"copper fluoride"/(0.600*L)#

And #n_"copper fluoride"=0.250*mol*cancel(L^-1)xx0.600*cancelL#

#=# #0.150*mol" copper fluoride"#

#"Mass of cupric fluoride"# #=# #0.150*molxx101.54*g*mol^-1# #=# #??g#
