37
You actually just answered your own question. The Isotope Ar-37 has a mass of 37. Most elements and Isotopes are commonly phrased like "Element-Mass"
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
Argon is a non metal element. Atomic number of it is 18.
The atomic number of argon is 18, which means it has 18 protons in its nucleus. The mass number of argon is 40, which is the sum of protons and neutrons in its nucleus.
The mass number of Argon is 39.948 so it is 119.98/39.948=3.0034 moles of Argon in 119.98 g of Argon or approximately 3 moles of Argon is in 119.98 g this gas.

It is 40!
The number of neutrons in an argon atom is 22. This is calculated by subtracting the atomic number of argon (18) from its atomic mass number (40).
The relative atomic mass is 39.95
The element with a mass number of 37 is chlorine (Cl).
