how to find eV

[Elizabeth Kakachyan 1C]

Hello,
One of the problems on the homework asks for the energy in electron volts. How do you convert from J to eV? Thanks!

[205484435]

Hi,

1eV = 1.602*10^-19 J

You can also find this on the constants and equations sheet.

[Tanvi Akula 2K]

On the constants sheet, you can find the conversion factor which is 1eV=1.602*10^-19 J.

[Madison Yee 2B]

1 eV (electron volt) is approximately equal to 1.60 * 10^19 joules.

[Dana Sorensen 1C]

To convert from Joules to electron volts, you can check the constants and equations sheet. The ratio of Joules to electron volts is 1.602*10^-19 Joules to 1 electron volt. Therefore, to convert you should divide your Joules by (1.602*10^-19).

[Yewon Jang 3K]

Hi! 1 unit of eV is equal to around 1.60*10^-19 J. So, in order to find the number of eV when given the number of J you would multiply by that constant. Hope that helps!

[Joseph Lee]

I also agree with what everyone's saying, I would also just add that if you need any of these constants, or just need somewhere to find them, I would use the constants equation sheet that they gave us. it is all on there!

To convert from eV to J you use the conversion factor 1eV = 1.602*10^-19 J. So just multiply the eV value by 1.602*10^-19 J to get the quantity in Joules.

[Aashna Sibal 2F]

As others have said, you just use the conversion given on the constants and equations sheet. If you are given something in terms of joules, you have to divide by 1.602 x 10^-19 J to get the answer in terms of eV, since that's how many J are in an eV.

[Prithvi Raj 3E]

As others have said, an ev is simply a measure of energy. From class, we learned that the conversion is 1eV = 1.602*10^-19 J.

[Desiree Eshraghi 3A]

As others have said, it is a very simple conversion but easy to mess up if you're not careful! Always check the constants and equations sheet!

[Jayden Tan 2L]

Hi there!!

The Constants and Equations Sheet tells you that 1 eV = 1.602 * 10^-19 Joules!

Good luck with the homework :)

[Samantha Quevedo 2L]

Hello,
To find eV you just use 1ev=1.602*10^-19J

[Samir Panwar]

This is given on the constants and equations sheet where 1eV = 1.602*10^-19J.

[Carla Bruebach 1C]

To find eV use use the conversion factor: 1ev=1.602*10^-19J

So, # of Joules x (1eV/1.602*10^-19J) OR (# of Joules/1.602*10^-19J)

[Arden Napoli 1E]

Hi,

the conversion to find eV from joules is 1 eV = 1.602 * 10^19 J

[Mahika Saoji 3K]

Hi!
The constant sheet that is on Dr. Lavelle's website actually has the conversion, which is very helpful. Nonetheless, the conversion is this: 1 eV = 1.602 * 10^19 J.

[AndreyCastellanos 3H]

1eV = 1.602*10^-19 J

[Joshua Lance Yumul 1F]

To convert from joules to eV, the equation would be 1 eV = 1.602x10^-19 J. If you can't remember this from the top of your head, we have access to the constants and equations sheet during tests and hw!

[Bela Patel 2B]

There is a conversion factor of 1eV = 1.602*10^-19 J. You can also find this on the Equations sheet on Lavelle's class website.

[Aaron Martinez]

Hi, using the equation sheet one electronvolt is equal to 1.602*10 ^ -19 Joules, so if you have Joules, divide them by the number.

[dahlia Faruque]

Hi to find eV you would use the simple conversion factor which is:

1eV= 1.602 x 10^-19 Joules

[Sofia Potter 1I]

I think most conversion factors can be found on the "Constants and Equations" sheet! In this case the conversion is 1 eV = 1.602 x 10^-19 J.

[Maddie Klee 3K]

Hi!
This conversion should be on the equation sheet! Simply multiply the eV value by 1.602*10^-19J and you should have the value in Joules!

[Kaitlyn_Urquilla_1I]

Hi! If you go to the Constants and Equations sheet on the Chem 14A website, the conversion is on there. 1 eV = 1.602 x 10^-19 J

[Michelle Jeong 1B]

As others have said its 1eV = 1.602*10^-19 J but no need to memorize because it is on th equation sheet.

[Rishab_Haldar_3B]

To convert from J to eV, you use the conversion 1 eV = 1.602 x 10^-19 J.

[Zoe Apple 1F]

To go from J to eV, multiply the number of Joules by 1.602*10^-19 J. To do the opposite, divide by 1.602*10^-19 J.

[Sophia Dominguez 3I]

You can find the conversion factor on the constants sheet to convert J to eV. 1 eV = 1.602*10^-19 J. Specifically, you would need to divide your original solution (J) by 1.602*10^-19 in order to get the value in eV.

[Fiona H 2E]

1eV = 1.602*10^-19 J

[Madison Rhynhart 3H]

This is merely a constant that can be found on a constants sheet and indicates that for 1 eV there are 1.602*10^-19 J

[Emily Ngo 1E]

Hi Elizabeth,
We know that 1 eV is equal to 1.602 x 10^-19 J from our equations sheet. If the question asked for eV and you have Joules, you would just divide your value by 1.602 x 10^-19. 1 eV is also equal to 1.602 x 10^-22 KJ if you needed. Hope this helped!

[Julia Todorov 2F]

the conversion factor for eV is 1eV = 1.602*10^-19 J, which can be found on the constants and equations sheet! So if you want to convert jules to eV, you would divide the jules by 1.602*10^-19 J

[605537776]

You can find it by calculating for J first and then converting it to eV using the formula 1eV=1.602*10^-19 J.
