    No idea if they're right but your significant figures are way off.

    Haha i dont have a periodic table on me, but as long as you used the mass/molar mass=amount of moles formula, you should be fine

    They're all right apart from the last one. The fact that it's an ion is irrelevant - just do it exactly like the previous question and you'll be fine. You can immediately tell it's wrong since sulfur has a RAM of 32.1 and an eighth of that is already bigger than 4g.
