Answer: Option (1) is the correct answer.

Explanation:

Atomic mass or mass number means the total number of protons and total number of neutrons present in an atom.

Thus, the atomic mass of titanium is 47.88 this means that it includes the total mass of all the protons and neutrons in an atom of Titanium.

Since the atomic number or number of protons present in titanium are 22. Therefore, number of neutrons present in titanium will be atomic mass minus atomic number.

No. of neutrons = atomic mass - atomic number

= 47.88 - 22

= 25.88 ≈ 25 (approx)
