Question

molecular formulas are determined from the ratio of the compounds molecular formula mass to its ____________.stabilitysolubilityoverall chargeempirical formula massquestion 211 ptsa(n)_______________ is the sum of the average atomic masses of all the atoms represented in an empirical formula.empirical formula masscumulative ionic chargemolecular formula masssample mass

Explanation:

• For the first question: Molecular formula is related to empirical formula. The formula \(n=\frac{\text{Molecular formula mass}}{\text{Empirical formula mass}}\) is used to find the multiple \(n\) to get the molecular formula from the empirical formula. Stability, solubility, and overall charge are not directly used in this ratio calculation for molecular formula determination.
• For the second question: By definition, the empirical formula mass is calculated as the sum of the average atomic masses of all the atoms in the empirical formula. Cumulative ionic charge is about charges of ions, molecular formula mass is for molecular formula (not empirical formula context here), and sample mass is a different concept (related to the actual mass of a sample, not formula - based mass).

Answer:

First question: empirical formula mass.
Second question: empirical formula mass.
