Answer:
If you want to calculate the number of moles of any compund, you should look for the molar mass. For LiF, its molar mass is 25,9 g/m So if 25,9 g are in one mol, the 317 in how many?. Then 12,2 is the number of moles of lithium fluoride produced.
Explanation:
To get the molar mass of a compound, you should know the mass at the Periodic Table, for Li 7,00 , for F 18,9
Answer:
what is the question i don't understand
