To make 1.0 L of a 10.g NaCl/L solution, 10.g of NaCl is weighed and poured into a volumetric flask.What is the next step?
A) The next step is to measure out 1.0 L of water, pour it into the container, and mix.
B) The next step is to fill the container up to the top of the flask.
C) The next step is to fill the container to the 1.0 L mark while swirling to mix.
D) The next step is to transfer the NaCl to a new flask.
E) None of these.The solute should always be added to the container after the solvent, not before.

To prepare a solution of a specific concentration, the solute (in this case, NaCl) is added to a volumetric flask, and then solvent (usually water) is added up to the calibration mark (the 1.0 L mark in this scenario) to ensure the desired volume and concentration. Swirling helps to mix the solute and solvent effectively.
