1

2. Chiomatn93

how do u find the answer tho?

3. seashell

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

4. Chiomatn93

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

5. seashell

hmmm.. let me check

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 4 years ago Report Abuse Eric Best Answer - Chosen by Asker 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

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

8. Chiomatn93

ok thanks i'll try it out now

9. seashell

:D kay
