Answer:
It should be transferred to a Beaker to finish preparing the solution
Explanation:
NaNO₃ is sodium Nitrate. It is a salt that is soluble in water hence it's aqueous solution can be prepared by dissolving it in water.
A beaker is a laboratory glassware that is used for various functions; one of which includes the preparation of reagents or aqueous solutions of a compound. In the example narrated in the question, the measured NaNO₃ solid can be transferred to a 100 mL or 200 mL beaker and then added to it is the desired volume of water to make the solution 100 mL. This solution can then be stirred with a "glass rod"
