The atomic mass oftitanium is 47.88 atomic mass units this atomic mass represents the 1) total mass of all the protons and neutrons in an atom of ti 2) total mass of all the protons, neutrons, and electrons in an atom of ti 3) weighted average mass of the most abundant isotope of ti 4）weighted average mass of all the naturally occurring isotopes of ti

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)

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
