Question

Quizplus · Accepted Answer

The mole fraction of a solute in a solution can be calculated using the formula: mole fraction = moles of solute / (moles of solute + moles of solvent). First, calculate the moles of CaCl2 in 1 L of solution: 2.00 mol. Then, find the mass of 1 L of solution: 1.17 g/mL * 1000 mL = 1170 g. Subtract the mass of CaCl2 (2.00 mol * 110.98 g/mol = 221.96 g) from the total mass to find the mass of water: 1170 g - 221.96 g = 948.04 g. Convert the mass of water to moles (948.04 g / 18.015 g/mol = 52.63 mol). Finally, calculate the mole fraction: 2.00 / (2.00 + 52.63) = 0.0366.
