CH08 Required HW 11/ 02 Question (1 point) Calculate the molarity of each of the following: 1st attempt Part 1 (0.3 point) 69.0 g LiCl in 250.0 mL of solution Part 2 (0.3 point) 26.0 g NiSO4 in 200.0 mL of solution 1 OF 18 QUESTIONS COMPLETED

Answer 1

Part 1 moles of Licl = mass malar mass 69 = 1.628 moles 42.394 ma molari moles 1.628 - 250ml volume of solution in L 1.628 = 6.512 mol/L 250 8103 L = 6.512 mol/L Answer molarity

Part 2 PAGE moles of Nisou - - mass molal mass 26 154.75 = 0.168 moles malarity = moles volume of solution in L. 0.168 200 mL 200x153 L. = 0.168 molarity = 0.04 mol/L .84 mol Answer Part-3 moles of KCN = mass molar mass 49.5 = 0.760 moles 65.12 moles molarity = volume of solution in L 0.760 0.760 500 ML 500 X 16 3L 1.52 mol/L Answer Imolarity =
