From the equation C + 2H2SO4 → CO2 + 2H2O + 2SO2
Calculate:
(i) The mass of carbon oxidized by 49 g of sulphuric acid (C = 12; relative molecular mass of sulphuric acid = 98).
(ii) The volume of sulphur dioxide measured at stp. liberated at the same time. (Volume occupied by 1 mole of a gas at stp is 22.4 dm3)
