Problem 75AP
A cube made of platinum (Pt) has an edge length of 1.0 cm.
(a) Calculate the number of Pt atoms in the cube. (b) Atoms arc spherical in shape. Therefore the Pt atoms in the cube cannot fill all the available space. If only 74 percent of the space inside the cube is taken up by Pt atoms, calculate the radius in picometers of a Pt atom. The density Pt is 21.45 g/cm3, and the mass of a single Pt atom is 3.240 × 10-22 g. [The volume of a sphere of radius r is ]
