The number of coulombs of positive charge can be calculated using the formula Q = n * F, where Q is the charge in coulombs, n is the number of moles, and F is Faraday's constant (96,485 coulombs/mol).
One mole of O2 gas has a charge of 96,485 coulombs (equal to Faraday's constant) due to the presence of 2 moles of oxygen atoms, each with a charge of +1.
Since each oxygen atom in O2 gas has a charge of +1, there are 1.91 mol * 2 mol = 3.82 mol of positive charge present. To convert this to the number of electrons, we multiply by Avogadro's number (6.022 x 10^23 electrons/mol), giving us approximately 2.3 x 10^24 electrons.
No, the number of coulombs of positive charge in O2 gas is not affected by temperature or pressure. It is solely dependent on the number of moles of O2 gas present.
No, the number of coulombs of positive charge in O2 gas cannot be negative. Coulombs are a unit of positive charge, so it is always a positive value.
