Final answer:
To calculate the number of fundamental units of charge in 40.0 C, divide the charge by the elementary charge, 1.602 x 10^-19 C.
Step-by-step explanation:
The question asks how many fundamental units of charge, denoted as qe, are equivalent to a charge of 40.0 coulombs (C). The elementary charge, qe, is the magnitude of charge of a single proton or the negative of a single electron, which is approximately 1.602 x 10-19 coulombs.
To find the total number of fundamental charge units in 40.0 C, you divide the total charge by the magnitude of one elementary charge:
Total fundamental charges (qe) = Total charge (C) / Elementary charge (qe)
= 40.0 C / 1.602 x 10-19 C
This calculation results in the total number of fundamental charge units in 40.0 C.
