Step-by-step explanation:
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
