How do you calculate Delta E? [Fact Checked!]

WebSo, one liter is equal to one, ten to the minus third, meters cubed. So now our liters cancel out, and pascals times meters cubed, gives us joules. So that gives us, that delta U, or change in internal energy, is negative 485 joules, then if we plug this all into our calculator to calculate the work, we get positive 25.25 joules. WebScience Chemistry Use the Rydberg equation [Equation (5) in the procedure handout] to calculate delta E (in joules) for the line in the Balmer series of hydrogen where nouter = 4 and ninner = 2.
