Bass · Answer 1

100 mL volumetric flask.

Explanation:

For preparation of any solution we generally use volumetric flask.

We will weigh the required amount of NaCl (based on calculation for 100 mL of 0.422 M NaCl) and will add this in a 100 mL volumetric flask.

There is only one mark in the volumetric flask.

So we will start adding water to it through wash bottle.

Then will continue stirring the solution to dissolve NaCl with addition of more amount of water (use funnel to add water).

Then finally we will make up the solution to 100 mL of mark.
