Final answer:
The total volume of the solution formed is 23.9 liters.
Step-by-step explanation:
To calculate the total volume of the solution formed, we need to use the formula molarity = moles of solute / volume of solution in liters. Given that the molarity is 0.0300 M and the moles of NaCl is 42.0 grams / 58.44 g/mol = 0.719 mol, we can rearrange the formula and solve for the volume of solution:
Volume of solution = moles of solute / molarity = 0.719 mol / 0.0300 M = 23.9 liters
