after measuring the mass of a solid in a weighing vessel, what are the proper steps to add the solid to a volumetric flask for making a solution?
○ pour the solid from the weighing vessel directly into the flask.
● pour the solid from the weighing vessel directly into the flask, then rinse the weighing vessel to ensure all residual solid is added to the flask.
○ use a funnel through which the solid is poured into the flask, then rinse the funnel to ensure all is added to the flask.
○ us ough which the solid is poured into the flask.

Explanation:

To prepare a solution accurately, all the measured solid must be transferred to the volumetric flask. Using a funnel prevents spillage, and rinsing the funnel ensures no solid remains stuck to it, guaranteeing the full measured mass is added. Direct pouring risks loss, and rinsing only the weighing vessel without a funnel may still leave solid residue or cause spills.

Answer:

Use a funnel through which the solid is poured into the flask, then rinse the funnel to ensure all is added to the flask.
