Question What is the molarity of a solution that contains 2.93 g of NaCl dissolved in 0.025 L? 0.0012 M 0.050 M 1.3 M 2.0 M

Answer: 2.0 M Explanation: Step 1: Given data Mass of NaCl (solute): 2.93 g Volume of the solution: 0.025 L Step 2: Calculate the moles corresponding to 2.93 g of NaCl The molar mass of NaCl is 58.44 g/mol. 2.93 g × 1 mol/58.44 g = 0.0501 mol Step 3: Calculate the molarity of the solution Molarity is equal to the moles of solute divided by the liters of solution. M = 0.0501 mol/0.025 L = 2.0 M Log in to Reply

Answer:2.0 M

Explanation:Step 1: Given dataStep 2: Calculate the moles corresponding to 2.93 g of NaClThe molar mass of NaCl is 58.44 g/mol.

2.93 g × 1 mol/58.44 g = 0.0501 mol

Step 3: Calculate the molarity of the solutionMolarity is equal to the moles of solute divided by the liters of solution.

M = 0.0501 mol/0.025 L = 2.0 M
