kanafani (ak22724) – Homework 2 – Sutcliffe – (52440) 1 This print-out should have 20 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. Read the questions carefully. Look for whether youve been give or asked for moLaR- ity or moLaLity! The last half of the questions require you to consider the vant’Hoff factor i, for solutes that might dissociate into several ions, so read carefully. Assume ideal behavior of solutions in questions 13 through 18. This covers the remaining material on Exam 1. We will cover chapter 6 on Exam 2. 002 10.0 points What is the molarity of a solution composedof 9.815 g of HCl in 0.3472 L of solution? M = 0 . 269199 mol HCl 0.3472 L soln = 0 . 775343 M HCl 003 (part 1 of 2) 10.0 points A student investigating the properties of so-lutions containing carbonate ions prepared asolution containing 6.684 g Na2CO3in a flaskof volume 250 mL. Some of the solution wastransferred to a buret.What volume of so-lution should be dispensed from the buret toprovide 7.76 mmol Na2CO3? (part 2 of 2) 10.0 points What volume of solution should be dispensed from the buret to provide 9 . 059 mmol CO 2 3 ?
