✔ 最佳答案
1000*32%=320 tones=325120000gmolar mass of FeS2=56+32*2=120
so 325120000g contain 2709333 mole of FeS2
because there are 2 sulphur atom in each molecules
so mole of S=2709333*2=5418667 mol S
and each sulphuric acid molecules contain 2H, 4O, 1S
so mass=5418667(2*1+4*16+32)=531029366g=523 tonnes
