For the first five problems, you need to use the equation that says that the molarity of a solution is equal to the number of moles of solute divided by the number of liters of solution. To use the molarity equation, you need to convert grams of sodium chloride to moles of sodium chloride before you can use the molarity equation.
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 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 ...
Molarity is the number of moles of solute dissolved in one liter of solution. The units, therefore are moles per liter, specifically it's moles of solute per liter of solution. Rather than writing out moles per liter, these units are abbreviated as M and it means moles per liter (not just moles).
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.
