Question

Quizplus · Accepted Answer

The mole fraction of CaI2 is equal to the number of moles of CaI2 divided by the total number of moles of solute and solvent. The number of moles of CaI2 is 0.400 moles. The number of moles of water is 850.0 g / 18.015 g/mol = 47.19 moles. The total number of moles of solute and solvent is 0.400 moles + 47.19 moles = 47.59 moles. The mole fraction of CaI2 is 0.400 moles / 47.59 moles = 0.00841.
