Professor Organic Chemistry Tutor, thank you for a solid introduction to Mixture Problems in AP/ General Chemistry. Everything in life uses some form of Chemistry. Mixtures problems are common in all levels of Chemistry. The equation that's given in this video is a good starting point when solving mixture problems. This is an error free video/lecture on KZbin TV with the Organic Chemistry Tutor.

6:37 problem 2. What is the concentration of the mixture? The mixture is 200 L (50 from the 15% alcohol solution and 150 from the 35% alcohol solution). let y = percentage of alcohol concentration of the mixture, then y 200 L = the total amount of alcohol in the mixture. The first solution has 7.5 L of alcohol (50 x 15%) and the second solution has 52.5 L (15% x 150) and this equal to total alcohol in the mixture of y 200 L. solving for y will give the concentration of alcohol of the mixture, so 7.5 + 52.5 = y 200 or 60=y 200 or y = 6/20 or 3/10, 3/10 is the same as 30/100 or 30%. Therefore the mixture has a 30% alcohol solution. Ans 30% 10:03 alcohol solution or 60 L of alcohol is in it.

no because the factor was cuz of the increase of the second L to the total L. You have to consider than it is only one compound. Water is not included in the equation so it doesn't affect it. Try to do the same to other compounds. He said that it is only done when adding water to a pure, only.

Mass is conserved. Volumes of liquids are not necessarily. (10 L of A + 10 L of B will not necessarily produce 20 L of a mixture.) Differences can be significant. Without density data, isn't it better to use weights rather than volumes?

10:46. A student adds 60 liter of water to an alcohol solution of 20 liters and 28% alcohol . So the student adds 0 liter of alcohol to a solution that has 5.6 liters of alcohol (20 L x 28%) TO PRODUCE 80 liters (60 +20) of an unknown PERCENTAGE of alcohol. Let that unknown % of alcohol in the mixture = R so R% (80) liters of alcohol was in the final solution. Therefore 80 R% = 5.6 + 0 or 80 R= 5.6 or R% = 5.6/80 = 56/800 or 7/100 or 7%. Answer: the solution now contain just 7% of alcohol.13:49
