Which of these is always equal to the molar mass of any element?
2 answers:
Atomic weight, as it is essentially the same as mass
Answer: Option (b) is the correct answer.
Explanation:
Atomic weight is also known as atomic mass or molar mass of an atom.
Atomic mass means the sum of total number of protons and neutrons present in an atom.
For example, atomic mass of HCl is atomic mass of hydrogen + atomic mass of chlorine.
That is, atomic mass of HCl is 1.01 g/mol + 35.453 g/mol = 36.463 g/mol
Thus, we can conclude that molar mass of any element is always equal to its atomic weight.
