4.2

To find the mass of the cube, we first calculate its actual mass using its volume (27.0 cm^3) and density (10.3 g/cm^3): mass = volume x density = 27.0 cm^3 x 10.3 g/cm^3 = 277.1 grams. Since sterling silver is 92.5% silver, the mass of pure silver in the cube is 0.925 x 277.1 grams = 256.2 grams. Converting grams to ounces (1 ounce = 28.35 grams), the cube contains approximately 9.03 ounces of pure silver.
