Question

Questions number 42

as a conversion factor.
133.33 g AICI3
1 PmOT
6.02 x 1023 formula units
1 pmot
Substitute mass AICI3 =133.33 g, and sol
= 2.21 x 10-22
g AICI3/formula unit
3 EVALUATE THE ANSWER
The number of CI- ions is three times the number of Al3+ ions, as predicted. The mass
of a formula unit of AICI3 can be checked by calculating it in a different way. Divide the
sample mass of AICI3 (35.6 g) by the number of formula units contained in the mass
(1.61 x 1023 formula units) to obtain the mass of one formula unit. The two answers
are the same.
