Atomic weight/ mass = number of protons + number of neutrons
Neutrons and protons combined
There is no oxygen in a hydrocarbon, but the atomic weight is 16
the units for atomic weight are grams per mole. your question cannot really be answered correctly.
The atomic mass doesn't equal to the number of protons. The number of protons plus the number of neutrons equal to the atomic weight... DAI BI!
The atomic number of an element is equal to the number of protons in its nucleus. The atomic weight is the average mass of an element's isotopes, taking into account their relative abundance. Both the atomic number and weight can be found on the periodic table for each element.
Well, the neutrons AND protons are totaled together to equal the atomic weight!
atomic weight = mass of protons + mass of neutrons
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.

The atomic mass of an element is equal to its molar mass in grams/mol.
Not necessarily; the characteristic stated in the question is valid for atoms of equal atomic number, not atomic weight.

The formula mass of neon is equal to its atomic mass in atomic mass units (amu). This is because neon, like all elements, exists as individual atoms and its formula weight is the same as its atomic weight.
