How many moles of atoms are in 3.61 g Ni?
Answer in units of mol

Let's start by answering this question: What's the mass 1mol of Ni?

You find it the same way you find the mass of 1 mol of any element, by looking up the atomic weight on the periodic table. By definition, that's the mass (in grams) of 1 mol of the element.

So what's the atomic weight of nickel? If that's the mass of 1 mol, then how many mols is 3.61g?

Gee, thanks for the negative feedback. What exactly did you find NOT helpful about my answer? We're here to HELP you with homework, not to DO your homework for you. Sorry you weren't spoon-fed the answer. Maybe you should try putting the tiniest bit of effort into this yourself, rather than negatively impacting my reputation score.

Now if you still need help because you're unsure how to proceed even after reading my answer, I'll be happy to help you further. Just let me know where you're still having trouble, and save the "Not helpful" feedback for answers that are factually incorrect.
