[4 pts] Use your answer to problem 6 to estimate the mass% ethanol of a 160-gram distillate from the original 700-gram solution (200 g ethanol, 500 g water). This would be similar to collecting all four of the 40-g distillates in the same container. [2 pts] Without doing any more calculations, estimate the mass% ethanol of a 700-gram distillate from the original 700-gram solution. Explain your reasoning. Table 1 tracks the composition of a liquid solution (in the flask on the hotplate) and successive distillate samples. Unlike the multiple-stage distillation shown in Figure 3, wherein the liquid in the flask is replaced by the distillate, this example collects multiple distillates from the same liquid mixture. The original solution was 200 grams ethanol and 500 grams of water. Table 1: Each row represents the collection of one 40-gram distillate from the liquid solution. The composition of the liquid solution changes with each distillate. Distillate Mass Mole% sample (g) 1 700. 2 660. 3 620. 4 580.
