1. Calculate the number of moles of hydrogen produced. (each trial)Given:- Gas Constant (R) = 0.08205 (L*Atm)/(mol*K); units on the gas constant are Liters, Atmospheres, & Kelvins
- I'm told to convert my experimental values to the above's units to calculate properly
- Calculation of the number of coulombs passed: Coulombs = Amperes × Seconds
2. Calculate the Faraday’s Constant. (each trial)Given:- Determine the number of moles of electrons passed using the reaction stoichiometry
- Determine the number of moles of hydrogen gas produced
- F = couloumbs/mol
e-- I think this is the stoichiometry for my lab:
2H+(aq) + 2e- → H2(g) or H+(aq) + 1e- → ½ H2(g)I also need to provide:- Average (I can do this)
- Percent error
- Standard deviation (I can do this)
- Root mean squared
- Deviation for your experimental values of Faraday’s constant
3. Calculate the Avogadro’s Number. (each trial)Given:- Charge on a single electron= 1.60 X 10
-19 C
-I'm told to use my calculated value of the total charge passed during the reaction to calculate the total number of electrons consumed in the reaction at the cathode.
I also need to provide:- Average (I can do this)
- Percent error
- Standard deviation (I can do this)
- Root mean squared
- Deviation for your experimental values of Avogadro’s number
I would love it if someone helped steer me in the right direction to calculate what I am required above. All three trials don't need to be used to help me, but if someone can use just one of the trials for my calculations, I can replicate that across the other trials. I also don't need someone to calculate the answers, just help me formulate how to get there if that makes sense. And if willing, I would love to go over my calculations with someone to double-check my work.
I can provide my lab manual if anyone wants to see it. Any help is appreciated deeply!
