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.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
