Answer is: atomic masses.
For example, calculate molecular mass of one mole of ethanol (C₂H₅OH). Molecule of ethanol has two carbon atoms, six hydrogen atoms and one oxygen atom:
M(C₂H₅OH) = 2Ar(C) + 6Ar(H) + Ar(O) · g/mol.
M(C₂H₅OH) = 2·12 + 6·1 + 16 · g/mol.
M(C₂H₅OH) = 46 g/mol; molar mass.
Atomic mass is approximately equivalent to the number of protons and neutrons in the atom.

Answer:
1.69 × 10² ball bearings
Explanation:
The output of a plant is 4335 pounds of ball bearings per week (five days). The output of the plant per day is:
4335 lb/5 day = 867.0 lb/day
1 pound is equal to 453.592 grams. The mass in grams made each day is:
867.0 lb/day × (453.592 g/1 lb) = 1.911 g/day
Each ball bearing weighs 0.0113 g. The number of ball bearings made each day is:
1.911 g/day × (1 ball bearing/0.0113 g) = 1.69 × 10² ball bearing
Sodium Chloride is a example of a ionic bond one atom is positively charged while the other is negatively charged both end up becoming neutral charge after they bond. check my answer to make sure that statement is accurate.
