Answer : 2. "109.9446"
Explanation :

Answer: B) 109.9446 Explanation: The term gram formula mass is synonymous with molecular mass. So, to get this, we must add molar mass of all the elements in this compound.   Given compound is Lithium Sulphate - Li2SO4 Elemental calculation :: Li  -  Lithium   -   6.941    -     2   -   13.88200 %S  -  Sulfur     -    32.065   -    1   -   32.065 %O  -  Oxygen   -   15.9994  -    4   -   63.9976 % Now, total = 12.6264 + 29.1647 + 58.2090 = 109.9446    Hence, the gram formula mass of Li2SO4 = 109.9446.
