Question

check all that apply: 42.394 amu is the ____________ of lithium chloride. atomic weight molar mass molecular weight formula weight

Explanation:

Atomic weight refers to a single - atom property, not for a compound like lithium chloride. Molar mass has units of g/mol, not amu. Molecular weight is for covalent compounds, and lithium chloride is ionic. Formula weight is the sum of the atomic weights of all atoms in a formula unit of an ionic compound, and amu is a unit for formula weight.

Answer:

formula weight
