Avogadro's Number

Postby Baoying Li 1B » Mon Sep 30, 2019 10:18 pm

Hey, there. Just a minor question that is kinda bothering me. According to the textbook, it uses the Avogadro's number as 6.0221*10^23. However, during the lecture, Professor Lavelle uses 6.022*10^23. So, which one are we using?

I'm guessing we should go with what professor Lavelle says and follow his lead in using 6.022 instead of 6.0221. Although, I doubt it's significant enough that it will make much of a difference.

I personally use 6.022 x 10^23 and my answers are correct when I use this value. In addition, because Dr. Lavelle uses this value, I recommend going with it.

I have even seen it as 6.023X10^23 in other books but I'd say to stick with what Dr. Lavelle is using since it has been working with the class examples and the homework.

I used 6.022 x 10^23 in all the problems and I've gotten the right answer so I would say use that, especially if Dr. Lavelle uses it too.
