Answer 1

Answer #1

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)
