Li: atomic mass 6.941

F: atomic mass 18.998

Lithium fluoride is made up of these two elements. Its balanced formula is LiF (Li+1F-1). Adding both its atomic masses equals 25.939. Therefore one mole of LiF is equal to 25.939 grams. So, 1.5 moles of LiF is equal to 38.90 grams.

How many moles in 15 grams if lithium?

From the periodic table, lithium has an atomic weight of 6.941. The molar mass of an element is the atomic weight in grams. Therefore, 1 mole Li = 6.941g Li Therefore, moles Li = 15g Li X 1 mole Li/6.941g Li = 2.2 moles Li
