At a temperature of 214 K, carbon disulfide, CS₂, and acetone, CH₃COCH₃, are not fully miscible. Instead, they form separate liquid phases with mole fractions of carbon disulfide of 0.415 and 0.845. Use the lever rule to calculate the relative amounts of the two phases when 12.0 g of carbon disulfide and 12.0 g of acetone are mixed together at this temperature. Answers are reported as carbon disulfide : acetone.
