Calculate molality, molarity, and mole fraction of KI

Answer:
To calculate the molality (m), molarity (M), and mole fraction (χ) of KI (potassium iodide), we need to know the amount of solute (KI) and the solvent (usually water in this case).

  1. Molality (m):
    Molality is defined as the number of moles of solute per kilogram of solvent.

The formula for molality is:
molality (m) = \frac{n}{m_{solvent}}

where:

  • n = number of moles of solute (KI)
  • m_{solvent} = mass of the solvent (usually water) in kg
  1. Molarity (M):
    Molarity is defined as the number of moles of solute per liter of solution.

The formula for molarity is:
Molarity (M) = \frac{n}{V_{solution}}

where:

  • n = number of moles of solute (KI)
  • V_{solution} = volume of the solution in liters
  1. Mole Fraction (χ):
    Mole fraction is defined as the ratio of the number of moles of a component to the total number of moles of all components in the mixture.

The formula for mole fraction of KI is:
χ_{KI} = \frac{n_{KI}}{n_{solvent} + n_{KI}}

where:

  • n_{KI} = number of moles of KI
  • n_{solvent} = number of moles of solvent

By using the given amount of potassium iodide and the properties of the solvent, you can easily calculate the molality, molarity, and mole fraction of KI in the solution.
