What is the formula and molar mass of beryllium chloride?
Recall that the formula mass is the sum of the atomic weights of the atoms in substance while it is in its empirical formula, and that the atomic mass is the weight of precisely one mol of the substance.
We have Beryllium chloride which is an ionic compound that forms a crystal lattice, the formula
Since this is an ionic compound,
It's mass is 79.9175 amu.
