Molar mass is the sum of the ___ ___ of each atom in the compound. Also known as molecular weight or molecular mass.
atomic masses
Mass percent formula
= (mass part/mass whole)*100%
Empirical formulas are formulas derived from __ ___ data.
mass percent
Steps for finding the empirical formula
- determine the mass (g) of each element from mass%
- convert the mass of each element to moles and use the atomic mass of each element as the conversion factor
- divide all of the moles by the smallest number of moles
Molecular formula is the ___ formula multiplied by an integer
empirical

Solute that increases the electrical conductivity of a solvent WHEN ADDED TO A SOLUTION is called a(n) ___.
electrolyte
Solute that does NOT change the electrical conductivity when added to a solvent is a(n)
nonelectrolyte
When a(n) ___ substance dissolves in water, it breaks up into its component Ions, which makes it a strong ___ regardless of how soluble it is.
ionic, electrolyte
Substances that dissolve only to give molecules in a solution are/aren’t conductive and therefore are non/electrolytes
aren’t, nonelectrolytes
All molecular substances dissolve as molecules, true or false?
False
All ionic compounds are strong electrolytes, true or false?
True, because they will produce virtually nothing other than ions.
