Vedclass · Answer

(B) The compound contains $8\%$ sulfur by weight,meaning $8 \, g$ of sulfur is present in $100 \, g$ of the compound.To find the minimum molecular weight,we assume there is at least one atom of sulfur (atomic mass $= 32 \, u$) per molecule.Using the unitary method: If $8 \, g$ of sulfur corresponds to $100 \, g$ of the compound,then $32 \, g$ of sulfur corresponds to $(100 / 8) 	imes 32 = 400 \, g$ of the compound.Therefore,the minimum molecular weight is $400 \, g/mol$.

$A$ compound contains $8\%$ sulfur by weight. The minimum molecular weight of the compound is:
