A graduated cylinder (measuring cylinder) contains 27 mL of water at 25 °C and the mass of the water is 26.92 g. A sphere of iron with a diameter of 18.0 mm is added to the water in the graduated cylinder. The total mass of the water and the iron is 50.92 g. (The volume of a sphere is given by the expression: V = (4/3)ar³). (i) Calculate the total volume of the water and the iron in the graduated cylinder. (ii) Determine the density of iron at 25 °C? Show your calculations. (iii) Without doing any calculations, what do you think the density of 48.00 g of iron is at the same temperature? Explain your answer.
