When converting moles to atoms, I usually just use 6.02*10^23. However the solutions manual uses 6.022*10^23 and so my answers do not match up exactly with the solutions manual. Should I always be using 6.022 instead of 6.02? Or does it depend on the problem and how many sig figs the problem provides?
Since the textbook uses 6.022*10^23, it would probably be better to use that value so your answers can be more precise and line up with the textbook answers. In addition, it is a constant value so its sig figs are not dependent on other components of the problem.
Avogadro's number has a constant value of 6.022 x 10^23. Because Avogadro's number is constant, its significant numbers in any given problem would not change. You can use either 6.02 x 10^23 or 6.022 x 10^23 but, since the solutions manual uses 6.022 x 10^23, I think it would be better to use that value. Additionally, it provides you with a more accurate value. Hope this helps!
