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?
