Question

2. Using the data listed for aluminum in Table 1, a. Calculate the volume of one aluminum atom, va b. Calculate the volume of one mole of aluminum atoms, Vm in the liquid element.

Answer 1

Aus Atoms are spherical in shape Volume of sphere = 4ar r = radius of sphere Here we have - rudius of Aluminium atom = 1.431 x 108 cm volume of 1 Al-atom = 4 x 3.14 x (1.431×108) X S - |- 22 x 10 cm3 * No. of atoms in Imole = NA= 6.023x102 atoms. . Volume of Imole of Al volume of I 1 Al-atom x NA = 1.23 x1623 x 6.023 x 1023 = 7.40 cm3 Please Rate
