Final answer:
To determine the volume of hot absolute ethanol needed for recrystallization, you can use the formula: Volume of solvent = Mass of solute / Density of solvent. A graduated cylinder can be used to measure the volume of hot absolute ethanol.
Step-by-step explanation:
In order to determine the volume of hot absolute ethanol needed for recrystallization, you would first need to know the amount of solute that needs to be dissolved. Once you have that information, you can calculate the volume needed by using the formula:
Volume of solvent = Mass of solute / Density of solvent
To measure the volume of hot absolute ethanol, you can use a graduated cylinder. The size of the graduated cylinder will depend on the expected volume of the solvent needed for recrystallization.
