Question

Which of the following solutions contains the greatest number of ions?

1) 200.0 mL of 0.10 M iron (III) chloride
2) 800.mL of 0.10 M sucrose

Answer 1

1

Answer 2

how do u find the answer tho?

Answer 3

chloride has 18
sucrose has 12...
so chloride has more

Answer 4

is there an actually formula for finding the answer? i must show my work

Answer 5

hmmm.. let me check

Answer 6

ok look.. For example:
Which of the following aqueous solutions contains the greatest number of ions?
Choices:
A. 300.0mL of 0.10M CaCl2
B. 200.0mL of 1.10M FeCl3
C. 800.0mL of 0.10M sucrose
D. 200.0mL of 0.10M KBr
E. 400.0mL of 0.10M NaCl

M = moles per liter

Multiply M by L (300ml = .3L) and you get moles.

Multiply the moles by the number of ions

Example
0.10M CaCl2 x 0.3000 = 0.030mol CaCl2.

CaCl2 = three ions in solution

3x0.03 = 0.09mols of ions

Answer 7

does this help? its an example.. tell me what you get for your question

Answer 8

ok thanks i'll try it out now

Answer 9

:D kay

Answer 10

but how many ions are in iron (III) CHLORIDE? and in sucrose?
