The answer is 62.3.
That is the formula weight of magnesium fluoride (MgF₂), rounded to one decimal place, is 62.3 amu.
Formula weight of magnesium fluoride (MgF₂):
That can be calculated as:
=Molar mass of magnesium + 2×Molar mass of fluorine
=24.30 +2×18.99
= 62.28
So the answer is formula weight of magnesium fluoride (MgF₂), rounded to one decimal place, is 62.3 amu
