Each atom in a mole of water vapor (H₂O) has one electron removed. What is the total charge of the ionized gas? A) 96 kC B) 290 kC C) 600 kC D) 190 kC

Question

Quizplus · Accepted Answer

Each water molecule has 3 atoms (2 hydrogen and 1 oxygen). In a mole of water, there are Avogadro's number (6.022 x 10^23) of molecules, so there are 3 times that number of atoms. Removing one electron from each atom results in a total charge of 3 x 6.022 x 10^23 electrons. The charge of one electron is approximately 1.602 x 10^-19 coulombs. Therefore, the total charge is 3 x 6.022 x 10^23 x 1.602 x 10^-19 C = 290,000 C or 290 kC.
