發問:
What mass of sulphuric acid can be obtained from 1000 tonnes of an ore which contains 32.0% of FeS2?
最佳解答:
1000*32%=320 tones=325120000g molar 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
