<u>Answer:</u> It is equal to the sum of number of neutrons and protons.

<u>Explanation:</u>

Atomic mass of an element is defined as the sum of number of neutrons and number of protons that are present in an atom. It is represented as 'A'.

A = Atomic mass = Number of neutrons + Number of protons

For an element X having 5 protons and 6 neutrons, the atomic mass will be:

Atomic mass = 5 + 6

Hence, this is equal to the sum of number of neutrons and protons.

Why do we use a double arrow in the dissociation equation for a weak acid answer?
Zepler [3.9K]
Answer is: because weak acids do not dissociate completely.

The strength of an Arrhenius acid determines percentage of ionization of acid and the number of H⁺ ions formed. <span>
Strong acids completely ionize in water and give large amount ofhydrogen ions (H</span>⁺), so we use only one arrow, because reaction goes in one direction and there no molecules of acid in solution.

For example hydrochloric acid: HCl(aq) → H⁺(aq) + Cl⁻(aq).

<span> Weak acid partially ionize in water and give only a few hydrogen ions (H</span>⁺), in the solution there molecules of acid and ions.

For example cyanide acid: HCN(aq) ⇄ H⁺(aq) + CN⁻(aq).
