about 30.0 g it is actually 29.88 g hope it helps so about 30 g 

Answer: Molar mass of lithium oxide is 30.0 g

Explanation:  Molar mass of a compound is the sum of atomic masses of all the atoms present in it.

Lithium oxide, [tex]Li_2O[/tex] has two Li and one O atom. From periodic table, atomic mass of Li is 6.94(round to 7.0) and the atomic mass of O is 16.0.

So, molar mass of Lithium oxide = 2(7.0)+16.0

= 14.0 + 16.0

= 30.0

Hence, the correct choice is 30.0 g.
