# Calculate 0.2 ethanol mole fraction solution

Question

At 293K, what volumes of pure ethanol and water are required to make 1 liter of a solution of ethanol and water with a 0.2 mole fraction of ethanol?

Data: At 293 K, the density of ethanol is 0.789 g/cm3 and the density of water is 0.998 g/cm3. For a solution of ethanol and water with a 0.2 mole fraction of ethanol, the partial molar volume of water is 17.9 cm3/mol and the partial molar volume of ethanol is 55.0 cm3/mol.

Summary

The question belongs to Chemical Engineering and it is about the volume of pure ethanol and water solution for 0.2 mole fraction of ethanol. The data about density of ethanol and water has been given and the calculations have been clearly given in the solution.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
