Thank you for the opportunity to help you with your question!
Hi, Simplyamazin! So what
we need to do to find the moles is take the atoms of nickel over the atoms per
So: (7.5 * 10 ^15)/ (6.02 *10^23) = 1.25
* 10^-8 moles
Now, we need to convert moles to grams.
When we look at the periodic table, we see that there are 58.7 grams per mole
of Nickel (look at atomic weight). Now we just need to multiply the atomic
weight (grams per mole) by the amount of
moles we have (1.25 *10^-8)
This gives us: (1.25 * 10 ^ -8) * 58.7 =
7.3 * 10 ^ -7
Hope this helps!
