Kool-Aid Lab Concentration Concepts

Mr. Pacheco guides students through a lab to determine the molarity of Kool-Aid solutions. The lab involves preparing three different concentrations of Kool-Aid, using materials like Kool-Aid powder, water, and graduated cylinders. Students will learn to calculate the molar mass of sugar, using the formula C6H12O6, and perform related calculations. The video emphasizes understanding the conversion between liters and milliliters and the importance of accurate measurements.
