Answer:

#Li_2O# has a molecular mass of #29.88# #g*mol^-1#

Explanation:

So to get the mass of #4.500# #mol#, we simply mulitply the molar mass by the number of moles:

#29.88# #g*cancel(mol^-1)# #xx# #4.500# #cancel(mol)# #~~# #130*g#.

Lithium oxide also has the mineral name of anti-fluorite, where fluorite is #CaF_2#. Given that both materials have the same structure, why is #Li_2O# known as antifluorite?
