Answer:

Approx. #250*g# of salt.

Explanation:

We simply take the molar quantity, and multiply this by the molar mass:

#4.40*cancel(mol)xx(22.99+35.45)*g*cancel(mol^-1)# #=# #??*g#

From where did #(22.99+35.45)# come? What is the mass of an equivalent molar quantity of #LiF#? Should it have greater or less mass than the above; why?
