Determine the number of moles in each of the following?

(A) 4.00 x 10^20 atoms lead

(B) 1.49 x 10^23 formula units sodium hydroxide

(C) 1.17 x 10^25 copper(II) ions

Answer 1

Well...one mole specifies..#6.022xx10^23# #"individual particles"#

And so far (a) we gots a molar quantity of....

#(4.00xx10^20" lead atoms")/(6.022xx10^23*"lead atoms"*mol^-1)=6.64xx10xx10^-4*mol#...

What is the mass of this molar quantity...?

We see increasing molar quantities of (b) sodium hydroxide, and (c) copper(II) ions, but I will let you address these...

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
