What is the molas mass of lithium oxide li2o

Explanation:

Atomic mass means the sum of total number of protons and neutrons present in an element.

Molar mass is defined as the mass of one mole of a compound present in grams.  

For example, molar mass of is as follows.

      Molar mass of = 2 × atomic mass of Li + atomic mass of O

                                     =

                                     = 13.88 g/mol + 16.0 g/mol

                                      = 29.88 g/mol

Thus, we can conclude that molar mass of is 29.88 g/mol.
