Order the steps for creating a molar solution.

Question

Add water until the bottom of the meniscus reaches the line near the neck on the flask.
Rinse beaker with solvent and pour this into the volumetric flask.
Remove stopper and pour the solution into the volumetric flask.
Calculate the mass of the solute needed.
Add water to the solute to dissolve it.
Add stopper and swirl the flask.
Measure out the mass of solute needed.

Answer 1

Here is the correct order for creating a molar solution:

1. Calculate the mass of the solute needed.
2. Measure out the mass of solute needed.
3. Rinse beaker with solvent and pour this into the volumetric flask.
4. Add water to the solute to dissolve it.
5. Add stopper and swirl the flask.
6. Add water until the bottom of the meniscus reaches the line near the neck on the flask.
7. Remove stopper and pour the solution into the volumetric flask.

Note: Steps 3 and 7 involve handling the volumetric flask, which may lead to some overlap in practice, but it's typically not necessary to pour before adding solvent to the flask. The main sequence involves calculating and measuring the solute first, then dissolving, and finally adjusting the volume.
