A student was instructed to prepare 250 mL of a 0.500 mol/L solution potassium permanganate. What is the correct order for this
Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7
- Calculate the mass required to make 250 mL of a 0.500 mol/L solution of potassium permanganate.
- Obtain the calculated mass in a 250 mL beaker.
- Dissolve the solid in 125 mL of distilled water.
- Transfer the solution into a 250 mL volumetric flask.
- Rinse the beaker and pour into the 250 mL volumetric flask.
- Top up the solution with distilled water until it reaches the 250 mL meniscus line.
- Stopper and invert the flask to mix.
- Obtain the calculated mass in a 250 mL volumetric flask.
- Transfer the solution into a 250 mL Erlenmeyer flask.
