Based on the data provided, 0.2375 L of water and 81.225 g of Kool-aid are required to make 237.5 mL of 1 M solution of Kool-aid.

What is molarity of a solution?

The molarity of a solution is the amount in moes of a solute dissolved in a given volume of solution in litres.

  • Molarity = number of moles/ volume in litres

The moles and mass of solute is calculated using the formula below:

  • moles = mass/molar mass
  • mass = moles × molar mass

1 mole of Kool-aid = 342 g

Molarity of solution = 1 M

Volume of solution = 237.5 mL = 0.2375 L

number of moles solute = molarity × volume

number of moles of Kool-aid = 1 M × 0.2375 L = 0.2375 moles

Mass of Kool-aid required = 0.2375 × 342 = 81.225 g of Kool-aid.

Therefore, 0.2375 L of water and 81.225 g of Kool-aid is required to make 237.5 mL of 1 M solution of Kool-aid.
