In an experiment, you need 0.125 mol of sodium metal. Sodium can be cut easily with a knife (Figure 2.5), so if you cut out a block of sodium, what should the volume of the block be in cubic centimeters? If you cut a perfect cube, what is the length of the edge of the cube? (The density of sodium is 0.97 g/cm³.)

Data given in Figure 2.5
