A student wants to make 50-mL of a 0.6 mg/L solution of acetic acid. She will be making the solution by diluting a stock with a concentration of 2.0 mg/L. Put the steps for her dilution in order. 4. Cap the flask and invert several times to mix. 2. Fill the volumetric flask with deionized water until the meniscus touches the mark. 6. Swirl the flask to mix the contents. 1. Obtain a 50-mL volumetric flask. 3. Use a pipet to add the appropriate volume of stock solution to the flask. 2. Add approximately 10 mL of deionized water to the empty flask.
