During dilution process, what do you do if you add a bit too much solvent when filling the volumetric flask to the mark? O Calculate the equivalent amount of salt and add that to the solution O Remove the excess content of the flask until the volume matches the calibration mark Start over, the solution cannot be saved OUse a distillation unit to evaporate the excess solvent

Ignore my calculations that are already on there, but I'm struggling on this one and a step by step would really help me out. Thank you!
A student is preparing 0.5 L of a 0.1 M magnesium chloride solution. The student uses the following steps to get started. Step 1: Gather a graduated cylinder, balance, and stirring rod. Step 2: Calculate the number of moles of magnesium chloride needed. Step 3: Add enough water to reach the 0.5 L mark of magnesium chloride solution and stir until dissolved. Step 4: Label the solution 0.1 M MgCl2. The process as described is incomplete. What would fix the process so that it is accurate? A The student made a mistake in Step 1 by getting a graduated cylinder. The student should have gotten a beaker. B The student made a mistake in Step 2 by only calculating the moles of magnesium chloride. The grams should also be calculated to make the solution. C The student made a mistake in Step 3 by adding enough water to reach 0.5 L mark of solution. Exactly 0.5 L of water should have been added. D The student make…

b. Account for this fact: Mixing 50 mL of methanol with 50 mL of water produces a solution with a volume slightly less than 100 mL. OMethanol evaporates during the mixing. ODuring hydration, methanol molecules decrease in volume. Owater evaporates during the mixing. Owater molecules interact extensively with methanol molecules.

B. Determining the Composition of a Mixture of Sodium Chloride and Sodium Nitrate Partner I Prepare a solution of sodium chloride + sodium nitrate and indicator. Obtain a dropper bottle of potassium chromate (indicator) solution. To a clean and dry 125 mL Erlenmeyer flask, add about 40 mL of water and 8 drops of indicator solution. Weigh out approximately 0.05 grams of sodium chloride + sodium nitrate solid and record its exact mass. Dissolve the solid in the solution from step 1, stirring with a stirring rod to ensure complete dissolution. Determine and record the total mass of the Erlenmeyer flask and solution, noting the balance that you use to weigh. Rather than measuring the volume of silver nitrate solution added as in Part A, we will measure the mass of titrant added and make use of the weight-percentage concentration of silver nitrate in calculations. Prepare the silver nitrate solution. Obtain about 15 mL of 1.70% w/w silver nitrate solution in a 50 mL beaker. Designate a…
