Questions & Step-by-Step Solutions

What is the molarity of a solution containing 58.5 g of NaCl in 1 liter of solution? (2021)
  • Step 1: Identify the mass of NaCl in the solution, which is 58.5 grams.
  • Step 2: Find the molar mass of NaCl. The molar mass is 58.5 g/mol.
  • Step 3: Calculate the number of moles of NaCl using the formula: moles = mass (g) / molar mass (g/mol). So, moles = 58.5 g / 58.5 g/mol = 1 mol.
  • Step 4: Identify the volume of the solution, which is 1 liter.
  • Step 5: Use the molarity formula: Molarity (M) = moles of solute / liters of solution. Here, M = 1 mol / 1 L.
  • Step 6: Calculate the molarity: M = 1 M.
