Hi pallavi,

Let the compound be sxcly

no of moles of Sxcly=0.1

therefore,S atoms=0.1×X

              cl atoms=o.1×y

no of moles of Pbcl2 =o.1

therefore cl atoms=0.1×2=0.2

no of moles of BaSo4=0.2

therefore S atoms=o.2 moles

0.1× x=0.2




therefore the molecular formula of the compound is S2Cl2.
