Question

You have three sodium carbonate solutions on the lab table in front of you. All of the solutions came from a 500 mL volumetric flask containing 3.00 M sodium carbonate. Solution 1 contains 100. mL of the 3.00 M solution Solution 2 contains 50.0 mL of the 3.00 M solution Solution 3 contains 10.0 mL of the 3.00 M solution What is the new concentration of Solution 2 if 17.7 g of solid sodium carbonate (MM = 105.99 g/mol) is added and dissolved? (Assume no change in volume.) Multiple Choice 1.98 M 12.3 M 3.34 M 6.34 M 0.634 M
