Question

How many Cl- ions are there in 400.5 grams of AlCl3?

A. 9.000 ions
B. 1.500 X 10^-23 ions
C. 1.810 X 10^24 ions
D. 5.420 X 10^24 ions

Answer 1

Answer:

The answer to your question is letter A

Explanation:

Process

1.- Calculate the molecular mass of AlCl₃

Al = 1 x 27 = 27

Cl = 3 x 35.5 = 106.5

AlCl₃ = 27 + 106.5 = 133.5

2.- Find the number of ions of Cl using proportions

               133.5 grams of AlCl₃ ------------- 3 ions of Chlorine

               400.5 grams of AlCl₃ ------------   x

                x = (400.5 x 3) / 133.5

                x = 9
