20g of sulpher is present in 100g
then,32g of sulpher is presnt in 160g
                            so,mass of sulpher in the compound is 160g.
Now, most of the oxides with sulpher gives the ratio of 1:3(ratio of molecules)
So, if mass of sulpher is 160g mass of oxygen is 160x3=480g
                                 therefore,mass of the compound 160+480g=640g.
