40 g of sulfur, containing 20% impurities, burned out in atmospheric oxygen. Calculate the volume and amount of the substance of the released tetravalent sulfur oxide if its input was 70%.
S + O2 —> SO2m (impurities) = 160 * 0.25 = 40 gm (pure substance) = 160-40 = 120 g Find the quantity and volume of sulfur dioxide: n (S) = 120/32 = 3, 75 mol n (S) = n (SO2) = 3.75 mol V (SO2) = 3.75 * 22.4 = 84 l-theoretical Find the practical volume: V (practical) = 84 * 95/100 = 79.8 l
Answer: V (SO2) = 79.
