If aluminum has 13 protons, 14 neutrons and 13 electrons, what is its atomic mass? 26 14 27 13

27 is its atomic mass

Explanation:

Isotope in chemistry refers to a similar variant of same chemical element where they only differ in number of neutrons while the number of protons remains the same.

Since the aluminum isotope consists 13 protons and 14 neutrons, the mass number of the aluminum isotope would be equal to the sum of number of protons and neutrons present.

As there are 13 protons and 14 neutrons so the mass number will be equal to 27.

(75°f − 32) × 5/9 = 23.889°c

answer: b.
