What is the mass of solute in grams required to make 1 L of a 0.1 M solution of NaCl? (Molar mass of NaCl = 58.5 g/mol) (2021)

What is the mass of solute in grams required to make 1 L of a 0.1 M solution of NaCl? (Molar mass of NaCl = 58.5 g/mol) (2021)

Step 1: Understand that Molarity (M) is defined as moles of solute per liter of solution.
Step 2: Identify the desired molarity of the solution, which is 0.1 M.
Step 3: Determine the volume of the solution, which is 1 L.
Step 4: Calculate the number of moles of NaCl needed using the formula: moles = Molarity × Volume.
Step 5: Substitute the values: moles = 0.1 moles/L × 1 L = 0.1 moles.
Step 6: Find the molar mass of NaCl, which is given as 58.5 g/mol.
Step 7: Calculate the mass of NaCl required using the formula: mass = moles × molar mass.
Step 8: Substitute the values: mass = 0.1 moles × 58.5 g/mol = 5.85 g.
