The basic measurement of concentration in chemistry is molarity or the number of moles of solute per liter of solvent. This collection of ten chemistry test questions deals with molarity. Answers appear after the final question. A periodic table may be required to complete the questions. Question 1 What is the molarity of a solution containing 9.478 grams of RuCl3 in enough water to make 1.00 L of solution? Question 2 What is the molarity of a solution containing 5.035 grams of FeCl3 in enough water to make 500 mL of solution? Question 3 What is the molarity of a solution containing 72.9 grams of HCl in enough water to make 500 mL of solution?

Question 5 What is the molarity of a solution containing 72.06 grams of BaCl2 in enough water to make 800 mL of solution? Question 6 How many grams of NaCl are required to prepare 100 mL of a solution of 1 M NaCl? Question 7 How many grams of KMnO4 is required to prepare 1.0 L of a solution of 1.5 M KMNO4? Question 8 How many grams of HNO3 are required to prepare 500 mL of a 0.601 M HNO3 solution? Question 9 What is the volume of a 0.1 M HCl solution containing 1.46 grams of HCl?
