Homework Answers
Question 15. Option E
Explanation: 0.113 mol/(0.184 mol/L) = 0.614 L or 614 mL
Question 16. 0.0432 mol
Explanation: (548/1000) L * 0.0788 mol/L = 0.0432 mol
Question 17. Option E
Explanation: (65.5/1000) L * 0.21 mol/L = 0.013755*(6.023*1023) = 8.28*1021 aluminum ions
Question 18. Option E
Explanation: Sugar will not dissociate into ions but will just dissolve as molecules. Hence, sugar is a nonelectrolyte.
Question 19. Option D
Explanation: K2SO4(aq) + Ba(NO3)2(aq) ----> BaSO4(s) + 2KNO3(aq)
