Respuesta :
The solution which has the lower freezing point is 11.0 g of CH₃OH in 100. g of H₂ O
ethanol molality (m) = 2.38 m
The lower the freezing point of the solvent, the more concentrated the solution. As a result, increasing molality lowers the freezing point.
As a result, the freezing point of methanol is lower than that of ethanol.
what is freezing point ?
The temperature at which a liquid solidifies (freezes). Increased pressure, like increased temperature, usually raises the freezing point. In the case of combinations and some organic compounds such as lipids, the freezing point is lower than the melting point.
When a combination freezes, the first solid that forms has a different composition than the liquid, and the development of the solid affects the composition of the remaining liquid, usually in a way that slowly lowers the freezing point. This principle is used to cleanse mixes by progressively separating the components by successive melting and freezing. To freeze, the heat of fusion (see thermal fusion), or the heat required to melt a solid, must be removed from the liquid.
