Q:

What is the gram formula mass of ${Li}_{2} {SO}_{4}$ ?

A) 101.2487	B) 109.9446
C) 111.2687	D) 106.5871

Answer & 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 - ${Li}_{2} {SO}_{4}$

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.
