A cube made of platinum (Pt) has an edge length of 1.50 cm. The density of Pt is 21.45 g/cm3. (a) Calculate the number of Pt atoms in the cube. (b)Atoms are spherical in shape. Therefore, the Pt atoms in the cube cannot fill all the available space. If only 74.0 percent of the space inside the cube is taken up by Pt atoms, calculate the radius in picometers of a Pt atom. The mass of a single Pt atom...
