Scenario: Mobile_Manipulation
Instruction: Weigh 2g of Sodium hydroxide ($NaOH$) pellets at the workbench, move to the fume hood to dissolve them in a small amount of water, and finally transfer to the sink to dilute to 250mL in a volumetric flask.
Task abstract: Prepare a 250mL sodium hydroxide solution by weighing, dissolving, and diluting in designated lab areas.
