To convert weight to moles, we must use the molar weight found on the periodic table. Sulfur's (S) molar weight is 32.06 g/mol. Then we set up an equation and cancel out units:
[tex] \frac{1mole}{32.06g}*0.994g=0.031mol=3.1*10^{-2}mol [/tex]
So now we know that 0.994g of sulfur is equal to 0.031 moles.
