1. Calculate the number of moles in these quantities: (a) 25.0 g KNO3 (b) 56 millimol NaOH (c) 5.4 x 10° g (NH4)2C2O4 (d) 16.8 mL H2SO4, solution (d = 1.727 g/mL, 80.0% H2S0, by mass) 2. Which contains the larger number of molecules, 10.0 g H2O or 10.0 g H2O2? Show evidence for your answer. 3. In a blast furnace, iron (III) oxide reacts with coke (carbon) to produce molten iron and carbon monoxide: Fe,O3 + 30 How many kilograms of iron would be formed from 125 kg of Fe,03? 2 Fe + 3 CO
