Does one mole of copper have the same mass as one mole of iron? Explain.

Question

- I say no since:

1 mol Cu = 63.55g/mol

1 mol Fe = 55.85g/mol

So 1 mol of copper is 63.55g, while 1 mol of iron is 55.85g. So they have a different mass because their molar masses are different, right?

Answer 1

right!
