Molarity Practice Problems How many grams of potassium carbonate are needed to make 200 ml- of a 2.5 M solution? How many liters of 4 M solution can be made using 100 grams of lithium bromide? What is the concentration of an aqueous solution with a volume of 450 ml- that contains 200 grams of iron (Il) chloride * Molarity Practice Problems #1 Answer Key 1*. How many grams of potassium carbonate are needed to make 280 mL of a 2.5 M solution? Using the molarity equation (M = mol/L), we can find that we'll need 0.70 mol of potassium carbonate. Given that the molar mass of K2CO3 is 138.21 g/mol, this means that we'll require 97 grams 2

**Molarity** = moles of solute/liters of solution = 8/4 = 2. 2. A First convert 250 ml to liters, 250/1000 = 0.25 then calculate **molarity** = 5 moles/ 0.25 liters = 20 M. 3. C A solution with **molarity** 2 requires 2 M of N A OH per liter. So, 4 X 2 = 8 M. 4. A A solution of **molarity** 1.5 M, requires 1.5 mol of Na to every litre of solvent A teacher might teach problems where the molarity is calculated but ask for the volume on a test question. Note: Make sure you pay close attention to multiply and divide. For example, look at answer #8. Note that the 58.443 is in the denominator on the right side and you generate the final answer by doing 0.200 times 0.100 times 58.443 Practice: Molarity calculations.
