Density formula

In chemistry lab, a smdent was instructed to find the density of a rectangular piece of aluminum. After careful measurement, he recorded a mass of 31.44 g and a volume of 11.7 cm. Using the formula density = mass volume and a calculator, his answer was 2.6871794 g/cm. Which of these is the correct answer to report for the density of the aluminum ... [Pg.3]

In many cases of utilizing ionic conduction, the concentration Ci of ionic defects is constant, given by a dopant. For instance, ionic conductivity in yttria-doped zirconia is determined by the concentration of oxide ion vacancies, in turn given as charge compensating the yttrium acceptors, 2[vo ] = [Y ]. If the concentration of acceptors is given in mole-fraction, then it is necessary to multiply the resulting mole fraction of vacancies by the formula density or molar density of the compound in order to obtain the volume density required for insertion in Eq. 6.65 ... [Pg.160]
