Question

How many moles are 1.65 x 1022 atoms of Calcium?

Answer 1

Well, we can use the given information to reach that number. We do that like so:

First, we take the number number of atoms:

\[1.65 x 10^22\]

Then, we multiply this by Avagadro's Number:

\[1.65 x 10^22\] x \[6.02 x 10^23\]

so, there are about 9.93 x 10^45 moles!
