Question

Enter your answer in the provided box. Calculate the molarity of a solution prepared by diluting 65.88 mL of 0.469 M potassium chloride to 150.00 mL. IM

Answer 1

17 Dilution of solutions having been taken place. So, we can use standard Molarety equation, le, Miy=MqV2 Stock After dilution 0.469 465,86 = M x. 150mL M ML [M= 0.206M Thus, molarity of solution after dilution was found to be 0.206M

2) 6.40mL of 0.619M Nach 6.40 mŲ x 0.619 may 3.9616 mmol of Nach . Nace Natta . → 3.9616 mmol of nat Mexing with; 550 mL of 9.02x15²M 4 Nassou 49.61 mmol of Naz Soy ". Naz Sou 2Na+ + Soy?- (49.61) x2 = 99.22 mmol of Nat calculation of Molarity of Nat in solution Molarity = Total moles of Nat Total volume of solection = (3.9616 +99:22) nima (6.40 + 550 ) mL IM = 0.1854 ML Thus molarity of Nations are found to be 0.1854M
