Reference no: EM13168964

A solution made by dissolving 14.2 g of an unknown compound in 100.0 g of water has a freezing point of -0.771 °C. If the Kf for water is 1.86 °C/m, find the molar mass of the unknown compound. If the compound is 42.1% C, 6.48% H, and 51.4% O by mass find its molecular formula. Assume the compound is a non-electrolyte.
