Video transcript

To make a 2 mg/mL solution, dissolve 2 mg of solute in 1 mL of solvent. For larger volumes, scale proportionally: dissolve 200 mg in 100 mL, or 2 g in 1 L. Stir until fully dissolved. Ensure precision with a calibrated scale and appropriate measuring tools. Always follow safety guidelines and regulations when handling chemicals. Once mixed, label clearly and store under recommended conditions.**

Questions and answers

What is a 2 mg/mL solution?
A 2 mg/mL solution means that there are 2 milligrams of solute in every milliliter of solution. This is commonly used in lab settings for preparing chemical solutions.
How do I scale a solution for larger volumes?
To scale a solution for larger volumes, maintain the same concentration ratio. For example, to make 100 mL of a 2 mg/mL solution, dissolve 200 mg of the solute in 100 mL of solvent.
What equipment do I need to make a 2 mg/mL solution?
You will need a calibrated scale for measuring the solute, measuring cylinders or pipettes for the solvent, and a stirring tool to mix the solution thoroughly.
What safety precautions should I take when making solutions?
Always wear appropriate personal protective equipment, such as gloves and goggles. Work in a well-ventilated area and follow specific safety guidelines for the chemicals you are using.
