Answer:

The SI unit of quantity of electric charge is the coulomb.

Explanation:

The coulomb, #"C"#, is derived from the fundamental SI unit of time, the second, #"s"#, and the fundamental SI unit of electric current, the ampere, #"A"#. It is the charge #("Q or q")# transported by a constant current of one ampere in one second.
#"1 C"="1A"*"s"#

A coulomb is equivalent to the charge of approximately #6.242xx10^18# protons, or #1.036xx10^(−5)# mol of protons. Each proton has an elementary charge of #+1e#.
