Question

When given a compound, adding up all of the _______ of all of the individual atoms within one molecule of a compound will determine the molecular mass. A. protons B. electrons C. atomic numbers D. atomic masses

Answer 1

Atomic masses should be about right 

Answer 2

D. atomic masses

Step-by-step explanation:

Molecular formulas is the actual number of atoms of each element in the compound. Molecular mass is the sum of the mass of each element which is present in the molecular formula is multiplied by their subscript which appear in the molecular formula.

For example,

The formula is =
`C_4H_8O`

Mass from the formula = 4×Mass of Carbon + Mass of Hydrogen×1 + Mass of oxygen = 4×12 + 8×1 + 16= 72 g/mol

Thus, Correct option is - D. atomic masses
