- How many mL of HCI, 0.1 M, will you need to prepare 0.700 L of HCL, 0.025 M? Student A and Student were analyzing the initial set up of the first problem. Step 1: Identify and label knowns and unknown •Known Unknown M (initial) = 0.1 M V(initial) = ? mL M (final ) = 0.025 M V (final) = 0.700 L Step 2: Write the base equation for dilution M(1) x V(i) = M (f) x V (f) Step 3: Solve for the unknown and substitute the values. V(i) = (0.025 M)(0.700 L) = 0.175 L 0.1 M Student B said, "The dilution equation works, because the number of particles of solute that is transferred does not change during the dilution." Student A replied, "That is correct. You only add water to dilute the solution, so the number of solute particles does not change." You consider Student A and Student B to be correct.
