So (dds785) – 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. 001 10.0 points 26.6 g sodium nitrate is dissolved in water tomake 550 g of solution.What is the percent sodium nitrate in thesolution? 10.0 points What is the molarity of a solution composedof 7.074 g of HCl in 0.5874 L of solution? M = 0 . 194021 mol HCl 0.5874 L soln = 0 . 330304 M HCl 003 (part 1 of 2) 10.0 points A student investigating the properties of so- lutions containing carbonate ions prepared a solution containing 5 . 647 g Na 2 CO 3 in a flask of volume 250 mL. Some of the solution was transferred to a buret. What volume of so- lution should be dispensed from the buret to provide 7 . 168 mmol Na 2 CO 3 ? Correct answer: 33 . 6345 mL. Explanation: m Na
