What is the molarity of the solution? Ex 2: How many moles of solute are present in 1.5 L of 0.24 M Na 2 SO 4? 1. Calculate the molarity of 0.060 moles NaHCO 3 in 1500. mL of solution. 2. Calculate the molarity of 29.25 grams of NaCl in 2.0 liters of solution. 3. Calculate the molarity of 34 grams of sugar, C 12 H 22 O 11 in 500. mL of solution. 4.
molarity of a solution is equal to the number of moles of solute divided by the number of liters of solution. 1) In this problem, simply solve using the molarity equation to find that the
It is convenient to think of molar concentration as a conversion factor. If we have a solution that’s 12.0 M HCl(aq)—then that means: 1. Write out the two conversion factors for the following solutions: 3. What volume of solution (in both L and mL) contains the following amounts of solute? 2.
MOLARITY EXTRA PRACTICE WORKSHEET 1. What is the molarity of 2.0 L of solution made from 2.4 moles of NaCl and water? 2. What is the molarity of 500. mL of solution made from 0.70 moles of LiCl and water? 3. What is the molarity of 100. mL of solution made from 0.45 g of NaOH and water? 4. How many moles of NaCl are found in 2.2 L of a 0.300 M ...
Chapter 10 Molarity Practice Worksheet Using the definition of molarity, the given balanced equations, and stoichiometry, solve the following problems. 1. (Ca(OH) 2 aq) + H 2 SO 4 CaSO 4 (s) + 2 H 2 O l) a. How many L of 0.5 M Ca(OH) 2 (aq) are needed in order to have 5.5 mol of Ca(OH) 2? b. Find the number of mol of H 2 SO 4
What is the molarity of the following solutions given that: 1) 1.0 moles of potassium fluoride is dissolved to make 0.10 L of solution. 2) 1.0 grams of potassium fluoride is dissolved to make 0.10 L of solution.
MOLARITY WORKSHEET #1 For each of the following problems, use proper units and show ALL work: 1. If 10.7 grams of NH 4Cl is dissolved in enough water to make 800 mL of solution, what will be its molarity? (Answer: 0.25 mol/L). 2. Calculate the molarity of a solution prepared by dissolving 6.80 grams of AgNO 3 in enough
