Which of these are correct relationships?

-16 g sulfur =.5 moles of sulfur

-8 moles sulfur =.25 g of sulfur

-3 moles of sulfur = 64 g sulfur

- 96 g of sulfur = 4 moles of sulfur

I will assume here that we know the molar mass of sulfur, which is 32 g/mol (around).

this means that 0.5 moles will have half of it - the first option is correct!

8 moles will have 8 times this, which is 256 - the second option is not correct!

3 moles would have 96 grams - third option is not correct!

and we also know that 96 grams can't be 4 moles - so the forth option is not correct either
