When ethanol is added to water at 25 °C and 1 bar, the total volume of the solution changes according to the empirical function cm x - 0.36394 cm (mol EtOH) = ** V = 1002.93 cm + 56.6664 mol EtOH cm (mol EtOH) + 0.028256- where x is the number of moles of ethanol in the solution. As ethanol is added to the solution, the partial molar volume of ethanol decreases, reaches a minimum, and then increases. This behavior is shown in the figure below. Find the function for (ma) find the value x = ng 56 Ong TP How many moles of ethanol are present when the partial molar volume of ethanol in the solution is minimum?
