1)32g of O2= 2xNo atoms (No=avogadro no.)
20g " " =(2/32)x20 No=1.25 No atoms
44g of CO2=3xNo
1.25 No=(44/3)x1.25=18.33g of carbon dioxide
2)molar mass of BaSO4=233g
no. of moles of S in compound=no. of moles of S in BaSO4=NO. OF MOLES OF BaSO4 =1.158/233
amt. of sulphur in compound=(1.158/233)x16=0.07955
I hope this will help you
