Categorize the following polymers by polymer types. Possible answers 2 points Given the ionic radii and molar masses of Sc3+(0.88A,45.0g/mol) and F(1.24A,19.0g/mol), what value do you estimate for the density of ScF3, whose structure is shown below ? Refer to below for help. A=1108cm. Note all the atoms touch along the unit cell edge. The density of ScF3 is g/cm3. TABLE 12.1 Fraction of Any Atom as a Function of Location within the Unit Cell "It is only the position of the center of the atom that matters. Atoms that reside near the boundary of the unit cell but not on a corner, edge, or face are counted as residing 100% within the unit cell
