SUMMARY
The net charge of a substance with 5.4 x 1013 protons and 4.2 x 1013 electrons is calculated by subtracting the number of electrons from the number of protons. The correct calculation yields a net charge of 1.2 x 1013 protons, which corresponds to a charge of approximately 1.92 x 10-6 Coulombs, given that the charge of a single proton is +1.6 x 10-19 Coulombs. It is essential to reference the charge values for protons and electrons from a reliable source, such as a textbook.
